beancounter battle, high failcnt on privvmpages with Zimbra VE
type: item
description: Hi everyone I've been tinkering with this for a few days and still not got anywhere. Our server has 8GB physical memory and an 8GB swap partition running CentOS 5.4 on an Intel E7200 Core2Duo Got 1 VE up and running which is our Apache/PHP/MySQL intranet... I ran vzsplit -n 8 to generate this config so in theory this VE has 1/8th of the server resources The 2nd VE is meant to be a Zimbra mail container - I already knew Zimbra was a bit of a memory beast. But I just can't eliminate or even reduce the failcnt values I'm getting for this VE I calculated most of the resource parameter values for the zimbra VE by multiplying the apache ones created above by 7... in theory giving me 7/8ths of the physical machine. I noticed after various runs of vzsplit with different -n values that many of the paramters don't vary with the number of VEs so I kept those constant. I even tried -n 1 to make sure my values were sensible. vzcfgvalidate said that was ok so I started testing. The first test I tried I noticed the failcnts on privvmpages So I decided to up the limit of privvmpages, and again I got roughly the same number of failcnts Then I decided to try upping the limit to something massive... per this wiki http://wiki.openvz.org/Zimbra_on_OpenVZ_on_CentOS I upped the barrier and limit of privvmpages to 2147483647 and still got roughly the same number for failcnt ~17600 Also the failcnt shoots up in the first 1-2mins of VE start Here's the output of /proc/user_beancounters for that VE http://www.highbeeches.plus.com/zimbra_beancounters.txt And here's the zimbra VE conf http://www.highbeeches.plus.com/zimbra_ve_conf.txt I'd read up on all this already but thought I'd have a look at the OpenVZ User Guide PDF again and there's this section which is interesting Quote: vmguarpages: The memory allocation guarantee, in pages (one page is 4 Kb). VPS applications are guaranteed to be able to allocate additional memory so long as the amount of memory accounted as privvmpages (see the auxi…
