Too many packets in event queue, pausing

Wowza Streaming Engine
1

Hi … I have some questions about new Wowza Streaming Engine

I think new Wowza Streaming Engine is using a lot of CPU in one of my server

I have 3 server, server 1 and server 2 with Wowza 3.6.4 … in server 1 I have 580 user watching live streaming + DVR

CPU 81%

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND             
12065 root      20   0 12.7g 4.1g  13m S 81.8 12.9   2221:21 java

Server 2 (wowza 3.6.4) I have 250 users watching live streaming + DVR

CPU: 23%

 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                       
28152 root      20   0 6791m 375m 6880 S 23.4  2.4   8088:40 java

But in server 3 with Wowza Streaming Engine

Dell Dual Intel Xeon 5520

CentOS

64 bit

72GB RAM

Primary Disk: 120GB SSD

Im only have 120 users watching live streaming + DVR and my CPU is 530% !!!

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND                       
 2179 root      20   0 15.2g 3.4g  14m S 531.2  4.7   2369:05 java

I already set the Wowza for Production level

In my error log i got this:

Hi, sorry for the delay,

Are there any preceding ERROR lines? Have you perhaps manually deleted some of the DVR store?

It does seem to be DVR related, this post for reference

What is the current state of this problem?
