I have downloaded WSO2 MB recently and trying to start it but it is failing with below error.

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "CacheExpirySchedulerThread-97"

I have modified memory arguments to 512MB(actually I tried with different memory configuration also) but no luck. I am able to start other wso2 products on my machine without any problem. Please suggest.

More logs which are keep on coming are as below.

Answer 1

When you run the WSO2 Message Broker in Stand-Alone Mode (with internal Cassandra), you need more than 512 MB Memory. In my case only the startup took up to 700 MB.

Change the Memory in the bin/wso2server.bat File:

Please change this value as you have enough memory available on your system.

Answer 2

Found one solution is to run cassandra externally and fine tune it.
