zabbix_server memory leak

[jharr]

zabbix_server has a memory leak somewhere. Interestingly, it only happened to one process, the one which did most of the processing.

A simple restart fixed it. I didn't think to run an `lsof` before I killed it to see if there was any useful information there. I will if this happens again.

I'm compiling from source on an ubuntu 5.10 x86_64 box. My configure command looks like this:
./configure --enable-server --enable-agent --prefix=/home/zabbix/

Let me know if you need any more information.

Thanks,
James

This is interesting! We have several test systems running for months on Ubuntu 64bit and I see absolutely no evidence of a memory leak. Actually we
even did several tests regarding possible memory leaks before release of 1.1.

May I ask you to monitor memory usage of ZABBIX server? On server startup you may also see PIDs and names of the processes. I would appreciate if you could say what was the process.
