 Description   

vmware collector uses memory more than VMwareCacheSize. It seems that the process has memory leak problem.

StartVmwareCollectors=1
VMwareFrequency=60
VMwareCacheSize=8M

This Zabbix server monitor 1 vSphere 5.1 directly, and 7 VMs are working on the vSphere. vmware collector uses 120MB memory for 3 weeks, and continue to grow.

It seems that this issue duplicate to ZBX-7392.
I'm testing Zabbix 2.2.1 with ZBX-7392 fix for 6 hours. There is no memory leak so far.

wiper gnuregexp.c is used only on Windows. On *nix we are using the libc regular expressions.
