Subject Re: JAMES OOM, maybe the cause of MINA ?
Date Fri, 09 Apr 2010 10:40:06 GMT
Norman,

Couple of more queries

1. The heap dump uses circularqueue class, so seem to be taken for an
earlier trunk snapshot. Is my take correct?

2. What's the state of the System? are the clients receiving the
messages. The queue seems to be holding a very large number of
objects.
Essentially what I want to know is, if the clients are receiving the
messages or the Server is holding them up.

Will spend more time with the issue and see what I can figure out.

thanks
ashish
