OutOfMemory Error

Hi All,

We are facing Production server going down frequently due to below exceptions.

Exception 1:

Exception in thread "http-bio-8080-AsyncTimeout" java.lang.OutOfMemoryError: Java heap space
at java.util.concurrent.ConcurrentLinkedQueue.iterator(ConcurrentLinkedQueue.java:669)
at org.apache.tomcat.util.net.JIoEndpoint$AsyncTimeout.run(JIoEndpoint.java:157)
at java.lang.Thread.run(Thread.java:745)
Exception in thread "ajp-bio-8009-AsyncTimeout" java.lang.OutOfMemoryError: Java heap space
at java.util.concurrent.ConcurrentLinkedQueue.iterator(ConcurrentLinkedQueue.java:669)
at org.apache.tomcat.util.net.JIoEndpoint$AsyncTimeout.run(JIoEndpoint.java:157)
at java.lang.Thread.run(Thread.java:745)
Exception in thread "ajp-bio-8009-exec-937" java.lang.OutOfMemoryError: Java heap space
Exception in thread "ajp-bio-8009-Acceptor-0" java.lang.OutOfMemoryError: Java heap space

Exception 2:

Exception in thread "ajp-bio-8009-Acceptor-0" Exception in thread "Dispatcher-Thread-2" Exception in thread "ajp-bio-8009-AsyncTimeout" 
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "ajp-bio-8009-AsyncTimeout"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "ajp-bio-8009-Acceptor-0"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "Dispatcher-Thread-2"
java.lang.OutOfMemoryError: Java heap spaceException in thread "PegaRULES ManagementDaemon"

Even though we increased heap size we are still facing the same issue. Can any one let us know what can be done from server side to avoid this issue.

Thanks,

RakeshY
