Hi everyone!

I am recieving a bunch of messages like the following in my server.log:

Our client is using JBoss 3.2.1 on Windows 2000.

What is not shown in the log snippet above is that the server was running just fine 
immediately preceding these statements.  These errors occur fairly repetitively for 
the next hour and all major processing seems to have stopped.  The end users reported 
that they were no longer able to use the system.

I have looked through the forums and haven't seen anything to really explain this 
situation.  A lot of the posts that I have seen seem to relate this to an 
OutOfMemoryException, though I have not seen one in my logs.  It seems that this comes 
very much out of the blue.

A lot of responses to posts of this nature always say that the transactions are timing 
out because they are running to long.  I'm not going to say that is not happening, but 
the problem I see is that the same type of code execution had been happening for hours 
on end before these exceptions occured.

So here are some general questions I have about the situation, with any help greatly 
appreciated:

-Is there anything in 3.2.3/3.2.4 that would help with this situation?
-Does increasing memory help?
-Would this be most likely caused by a problem in my database driver (I'm using 
Firebird/Jaybird JCA)?
-Are there any configuration tweaks that can be done in order to tweak JBoss so that 
these errors are less likely to occur

Thank you in advance for your responses.

Regards,

Ben
