[jboss-user] [JBoss Seam] - Errors leading up to an out of memory situation

[modoc]

My Seam app has been running for almost a month without issue.  This morning it ran into any out of memory situation.  As it was a live site I had to just reboot instead of trying to figure out where the memory was being allocated or doing any diagnostics.  In the logs I see the following errors just before the out of memory situation happens.

I don't know that it is a cause and effect situation but the sequence is suspicious.  Any idea what this error means?

I also see several of these:
08:24:28,112 ERROR [[/10MinuteMail]] Session event listener threw exception
  | java.lang.ArrayIndexOutOfBoundsException


Any help would be appreciated.

Thanks!
