I confirm that there is a memory leak in ZABBIX 1.6 server code. Follow the link above for the absolutely correct fix.

Hi Alexei,

my server allways crashes after 24 hour. The server fills all swap on the machine. With Zabbix 1.4.6 the server runs without problems.

see log:

How long will it take to get a solution for this problem, because I have to downgrade next week to version 1.4.6.

It depends on speed of your Internet connection. Read carefully, solution is already here. Just download it!

I'm having a memory leak issue currently but I use MySQL and I dont' think the fix applies to my case (correct me if I'm wrong). I have a 3 node proxy configuration and I only see the problem on the central zabbix_server. The proxy servers seem to run just fine without undue memory usage.

I have as my central node a dual quad-core 2.3ghz machine, with 4GB RAM and 5GB swap. The server runs just fine but consistently fills up the memory and swap within 24 hours. This is an untenable situation as I'm monitoring over 1400 servers and restarting the zabbix_server daemon to clear the memory every 20 hours isn't going to let me go-live with Zabbix.

Any thoughts?

So, to answer my own question. Looks like yes. The fix does apply to MySQL too. Made the change, recompiled and it seems like it's doing ok so far.

Thanks all. I'll pop back in if the problem continues.
