Subject Re: OutOfMemory exception
Date Fri, 02 Apr 2010 18:56:39 GMT
Hi Eric

so at least the files not leak anymore, unfortunaly this was the less
critical problem.
About the errors in pop3server I will have a look and see what could
cause this. I'm 100 % sure it's not related to the OOM.

Any more infos related to the OOM are welcome.

Bye
Norman
