Our Windows Server 2008 R2 has both 32 and 64 bit versions on Java on it. I suspect that Wowza is using the 32bit version as I can’t set the Heap above 1500 without getting errors.

How can I force Wowza to use the 64bit Java?

Thanks.

On Windows you set the Java\_Home environment variable to point to the 64bit Java location.

Well that was easy enough. Done and working.

Thanks
