[Php-java-bridge-users] Java out of memory...

[<php...@li...>]

Hello all,

I've been building an application that provides a front end for a HP
product called service desk.  WE had this error last night,

      java.lang.Exception: Invoke failed:
[o(ApiOrganizationHome)]->findOrganization((IOrganizationWhere)o(ApiOrganiz=
ationWhere)).
Cause: Failed reading response from the server.
  Nested exception is:
        java.lang.OutOfMemoryError: Java heap space

I'm running the JVM as a service.

As far as I understand it, all java objects should be gabage collected
after a script finishes (no more references).  But I've been seeing
the resident memory usage of the Java service gradually increase as
the requests go in, and it doesn't go back down.

Anybody got any pointers or help they can give?

Thanks,

Paul.

Hi,

I think, the OutOfMemoryError happened in the EJB
business logic, not in the JVM running the bridge
backend. I assume the findOrganization is a EJB finder
method?

I haven't had OOM errors in the bridge backend for
some time now, but if I remember correctly the bridge
reports an OOM in its VM via:

JavaBridge ERROR: OutOfMemoryError

After that all clients should abort immediately
because the backend closes all connections to recover
from this. The above formatted error string ("Invoke
failed") makes me believe that it's not the bridge
backend that reported the OOM, but the component to
which the backend is connected, an EJB container
probably(?).

Can you please open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
 and attach the exception message from the
JavaBridge.log (on RHEL the log file is
/var/log/php-java-bridge.log) there?

We'll look at this asap.


Regards,
Jost Boekemeier
