Subject Re: OOM with Netty
Date Sat, 24 Apr 2010 14:23:06 GMT
Hi Eric,

just downloading it..

About the tread safety. I don't think so. I'm still wonder if the
exception was only thrown because of the OOM or if its the cause of
the OOM. Hopefully I will have a better view of the whole story once I
looked at the heap dump...

Bye,
Norman
