Hi,

After I increase the hibernate connection pool size from 1 to 4 and run my program, then I get the exception as following:

Code:
Exception java.lang.OutOfMemoryError: requested 16000 bytes for GrET* in D:/BUILD_AREA/jdk142-update/ws/fcs/hotspot\src\share\vm\utilities\growableArray.cpp. Out of swap space?


Could anyone tell me how to solve it?

Thanks in advance!

Regards,
Yulei

The JVMs I am familiar with allow you to specify the memory to be used. You can try increasing the memory to 256MB by passing the command -Xmx256m, for example.

Of course it is possible that you have some other problem in the code. If the above (or some other value) fixes the problem I would at least load test the app.

What I could not understand is that why hibernate use much more memory when increase connection pool_size from 1 to 4.

Any advice is appreciated.

It looks like a problem with your hardware or virtual memory configuration ( "malloc" fails ). Try to reproduce it on different mashine.
