I'm using zabbix 2.0 since the realease and also updated to the 2.0.1. AFor some time it happened that zabbix just stopped working without any reason, and i had to reboot it. after a while i decided to trace the zabbix server memory usage and thats what i discovered:
During the tiem zabbix simply start to eat all available memomy ultil there is simply not enough memory left for mysql to work ( causing mysql crash). In attachment a weekly memory usage. As you can see the available momory drop down. Everytime the available memory goes up its because i stopped and restarted zabbix_server.
My zabbix its on VM and i dont have swap space. If left zabbix working without periodical reboot it will eat all the memory until there is no memory for mysql and it cause DB to crash.
This server have no other stuff running except zabbix and mysql, and anyway the peak of available memory happened then i stop and start the zabbix server. Its a while im monitorig this behaviour and did several tests to be sure it was the zabbix server reboot that caused the abailable memory coming back.
For now, my workaround its to reboot it manually roughly every 2 weeks ( had to increase available memory from 4GB to 8GB just to be able to make zabbix last longer, but still will eat all the memory ).
