I also observed that the memory increaed way too fast when heavy loading.

Hey Mark, Based on the statistics I've been collecting from MINA I can tell that our OOM problems happen when: 1) the eventQueue instance variable inside of ExecutorFilter fills up (that would be the case for incoming traffic) or 2) the SocketSessionImpl#getScheduledWriteRequests() queue starts to fill up (that would be the case for outgoing traffic) Regards, -- Gato -----Original Message----- From: Mark Webb [mailto:[EMAIL PROTECTED] Sent: Wednesday, April 25, 2007 1:53 PM To: [email protected] Subject: Re: Permanent solution for OOM errors Maybe one approach would be to categorize the ways in which people reach OOM conditions. Do these conditions happen only when the input and/or output queues get really large, or are there other reasons. Once we can start to categorize the OOM conditions that users are experiencing, we can properly move forward with solutions. Basically what I mean is, if the OOM happens when queues fill up, then throttle filters would be best. If the OOM happen for other reasons, people could look at other areas of MINA. Just not sure there is one solution that will fix all the problems. ...just my 2 cents. -- ..Cheers Mark On 4/25/07, Gaston Dombiak <[EMAIL PROTECTED]> wrote: > Hey Marcin, > > I see what you mean.
