[xmlblaster] thread/mem leak?
Some days ago I began to experience OutOfMemoryExceptions with my XmlBlaster server instance. It's not the newest version (will try that now though). The interesting thing is that is began only a few days ago, before that there were no problems, I had my server running for many weeks. In my use case there are many non-persistent, small messages to one topic. After I got the exception I dumped the state of the server and the thread list looked like this (which, I think, is the cause for the problem):
Thread Group: main Max Priority: 10
Thread: XmlBlaster.MainThread Priority: 5
Thread: XmlBlaster.SessionTimer Priority: 5 Daemon
Thread: XmlBlaster.SocketDriver Priority: 5 Daemon
Thread: XmlBlaster.HttpIORServer Priority: 5 Daemon
Thread: Timer-0 Priority: 5 Daemon
[... lots of other normal things ...]
XmlBlaster.SSLSOCKET.SSL.tcpListener-poka Priority: 5 Daemon
[80+ more of this!]
So the user poka connects through SSL, and somehow it left a thread for every single login I did. The client automatically disconnects every time, and this user has a session timeout of a few ten minutes, so everything should be cleared at most one hour after the last activity of user poka.
What could have gone wrong? I can't stress enough that the XmlBlaster version did not change, nor did the configuration.
I'll try a new version from SVN right now. Also did increate max. stack size, but this does not fix the "thread leak" issue.
thanks for any tips,
