    Strange behavior when activating vmware pollers

    Hi,

    I'm currently running Zabbix 2.2.6 on my PRD environment (yes, I know, it's outdated, an upgrade is planned ).

    It's running smoothly, with these values :
    Code:
    Parameter	Value	Details
    Zabbix server is running	Yes	x.x.x.x:10051
    Number of hosts (monitored/not monitored/templates)	1251	1090 / 21 / 140
    Number of items (monitored/disabled/not supported)	149569	113798 / 2078 / 33693
    Number of triggers (enabled/disabled) [problem/ok]	55722	51246 / 4476 [588 / 50658]
    Number of users (online)	31	7
    Required server performance, new values per second	1312.96	-
    I'm running 300 pollers

    We're installing a VMware platform, and I wanted to monitor it, so I added to the zabbix_server.conf file the following lines :

    StartVMwareCollectors=5
    VMwareFrequency=60
    VMwareCacheSize=8M

    And that's when hell started.
    Immediately, the pollers were all busy (100%), and the zabbix frontend was displaying the infamous red label. On the dashboard, sometimes I could see that the Zabbix server was running (and still get the red ribbon), most of the time it was at not running, despite the fact that it was indeed running.

    I first thought it was due to a massive amount of data to retrieve, but after several hours, the situation was the same.
    Tried to restart, same result.
    I rollbacked the config, removed the vmware part.. and suddently everything went back to normal.

    I cannot believe that 5 vmware pollers can cause such a mess.

    Does someone already have that kind of problem ?

      It seems to be related to this bug, indeed.

      There was nothing specific in the logs, and with a test server running the 3.0.x version, it works just fine.

      Thanks
