# Could not reserve enough space for object heap.

Moved to a new VPS hosting. (server with 650 mb ram) I fresh installed the latest java JDK I fresh installed wowza 2 ```auto root@cpanel [/usr/local/WowzaMediaServer/bin]# ./startup.sh Error occurred during initialization of VM Could not reserve enough space for object heap Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. ``` I searched the wowza forums, and found threads suggesting to edit ```auto /usr/local/WowzaMediaServer/bin/setenv.sh ``` I did that. I think originally it was ```auto JAVA_OPTS="-Xmx768M" ``` I tried instead: ```auto JAVA_OPTS="-Xmx384M" ``` and also: ```auto JAVA_OPTS="-Xmx128M" ``` But I still get memory errors and Wowza won`t run. I have about 550 mb ram free. Any ideas, please? Thanks ---

Hi Is the Java version that you’re running 32bit or 64bit? I think this happens with 32bit. Jason ---

Take a look at this line in the log startup lines: ```auto Hardware Physical Memory: 275MB/1024MB ``` The VMS has 1024MB of RAM, but only 275MB is free. I think there is even less by the time java heap is allocated then Wowza continues to startup. This is just not a good server for Wowza. Richard ---

Try reducing the java heap size to 192M. It should start and have some streaming capacity. Richard ---

Right, sorry. So you already down to 128. Well, you have to keep going lower till it works. Even at 128 it is not a very useful streaming server anyway. Take a look at the Wowza partners page for other hosting options: [https://www.wowza.com/partners](https://www.wowza.com/partners) Richard ---

Hi Jason, thanks for answering I Installed the 64 bit rpm Java JDK on a 64bit server. I already unistalled wowza and reinstalled - problem persists! ---

That`s what I`m getting: ```auto root@cpanel [/]# java -version java version "1.7.0_03" Java(TM) SE Runtime Environment (build 1.7.0_03-b04) Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode) ``` I`m currently reinstalling wowza2 (3rd time) after having uninstalled+reinstalled JDK. When this is done I`ll look into the logs and be back to report, thanks ---

After having installed JDK and Wowza again, without errors and trying to run it as a standalone for the first time, instead of a prompt for Serial I get the usual error. The wowzamediaserver\_error.log was empty and these are the contents of the wowzamediaserver\_access.log right after the error: ```auto #Version: 1.0 #Start-Date: 2012-04-18 15:02:41 CDT #Software: Wowza Media Server 2.0.0 build22912 #Date: 2012-04-18 #Fields: date time tz x-event x-category x-severity x-status x-ctx x-comment x-vhost x-app x-appinst x-duration s-ip s-port s-uri c-ip c-proto c-referrer c-user-agent c-client-id cs-bytes sc-bytes x-stream-id x-spos cs-stream-bytes sc-stream-bytes x-sname x-sname-query x-file-name x-file-ext x-file-size x-file-length x-suri x-suri-stem x-suri-query cs-uri-stem cs-uri-query 2012-04-18 15:03:53 CDT server-start server INFO 200 Wowza Media Server 2 Developer 2.0.0 build22912 -

Following your suggestion, Richard, I gave up my previous attempt to move to this new host, and stayed with my previous one. 2 months gone by and I`m trying again, on a new server and having the exact same problem with yet another host. The first time it was Mochahost, now it`s vpsLatch. The strange thing is that both hosts offer packages with 1024 RAM and the current host on which Wowza is running without problem has only 768 RAM ! I installed wowza without errors on the new host but when trying to start it I got: ![](http://www.eomund.com/wowza_error_1.JPG) Then I edited the bin/setenv.sh to: ```auto JAVA_OPTS="-Xmx128M" ``` Then I tried running it again and this time I get: ![](http://www.eomund.com/wowza_error_2.JPG) (The Log error I get is only because I tried editing the Log4j.properties file in order to get a log of the problem and did a bad job, I need to fix that) But this time it says 285mb out of 1024 (whereas in the previous host, it said 275MB out of 1024MB) Does this host , too lack RAM or am I having here some other kind of a problem? Thanks ---

Hi JasonH, I suppose it`s VMware as the first error says: ```auto error occured during the initialization of VM ``` Not sure about what `production level` actually means. My current host is running Wowza and serving flv files without problem with only 768MB RAM. Are saying, JasonH, that I should be thankfull it`s running in the current host as it it`s not supposed to and that if I want to move to a new one I`d better make sure it has no less than 4 GB RAM, please? ---

Thanks Richard, Just to make sure I understand you correctly, Do you mean I should change inside setenv.sh to JAVA\_OPTS="-Xmx192M" from the current “-Xmx128M”? Or should I change it elsewhere? Thanks ---

I changed the heap size to 100, than 64 than 32 than 16 - same error no matter what. Richard, I must admit I`m very confused. How can it be that on Hostgator`s “VPS3” package of 768MB RAM everything is running without any error, with the original heapsize setting of 768M, and two new different servers who claim more RAM have the exact same error occurs no matter how ridiculously low I go with the heap size? I admit my knowledge and understanding of the java environemnt is nil. Still, I simply don`t understand how no amount of memory is low enough especially, as I`m not working it hard, just attempting to run without any load while on the `working server` it can carry the load of multiple clients requests. I cannot help but wonder if there is not a missing factor or setting here. I tried reproducing the same conditions as on the `working` server - such as installing JRE instead of JDK and then installing the same older JRE version (build 1.6.0\_18-b07) but to no avail. Thanks for the list of Wowza-partners but as far as I could understand they are rather streaming services and not low-cost VPS services on which I can install Wowza by myself, or if they are, prices are much higher than what I`m aiming at currently, while developping my environement I invested a lot of time and effort in adapting scripts and modules for Wowza to my needs, and maybe I`m on the step of giving it all up which to me is really sad. ---

Hi When Wowza starts up in stand-alone mode does it say in the logs that it’s using the 64bit architecture? There is a guide here, [https://www.wowza.com/docs/how-to-manually-install-and-troubleshoot-java-on-your-wowza-media-server](https://www.wowza.com/docs/how-to-manually-install-and-troubleshoot-java-on-your-wowza-media-server) Jason ---

Hi Start-up logs should look something like this: Java Name: Java HotSpot™ 64-Bit Server VM Java Vendor: Sun Microsystems Inc. Java Version: 1.6.0\_31 Java VM Version: 20.6-b01 Java Spec Version: 1.6 Java Home: C:\Program Files\Java\jre6 Java Max Heap Size: 682MB **Java Architecture: 64** Java Locale[user.language]: en Java Locale[user.country]: GB Note the bold “Java Architecture: 64” which is what you should be looking for.

Hi Yes I see that Java is running in 64bit, I take it you still have this problem after seeing that 64bit java is being used? So something else must be causing this problem then, I noticed that you are running Wowza 2.0.0 and it would be a good idea to upgrade. What happens when you type? (on the command line) : java -version Jason ---

Hi I think that 123MB is to low but Wowza should still run. What happens when you type? (on the command line) : java -version Jason ---

Hi What is the virtual environment that you are running? For example VMWare or Xen The minimum Wowza specs are here, **System Requirements** Minimum recommended production hardware CPU: Single Quad Core, 3.00 GHz or better RAM: 4GB Disk: 2 or more in RAID 0 (striping) Network: 1Gb Ethernet Supported operating systemsWindows® (XP, Vista, 7, Server 2003 & 2008) Linux (all distributions) Solaris Mac® OS Unix Java (required)Java Runtime Environment (JRE) 6 or greater or Java Development Kit (JDK) 6 or greater You should have 4GB of RAM at a minimum to run Wowza at a production level.

Maybe it Helps Idk i got the same error as u got , i just modified the Heap Size File on Wowza to 512 M then it started and i got the Java Error That u got Above then i Changed to 128 M and it simply worked no lags or something i am streaming with 4500 Kbps everything is alright , i bought a server with 10 Gbps Nic so now it goes very good
