Plesk's apache with SNI uses massive amounts of memory

[HostaHost]

So I've installed a few servers with the httpd rpm distributed by Parallels as part of 10.2 that has SNI support. Not sure what has been done in that one in comparison to the one from centos 5.6 but it reserves anywhere from four to ten times the memory.

Mem: 32938676k total, 24652480k used, 8286196k free, 1608220k buffers
Swap: 4192956k total, 119644k used, 4073312k free, 16220512k cached

It does this as soon as it starts so it's not some customer's php app causing the consumption. Same configuration with the centos httpd and it may consume 150 to 400 MB.

I have discussed with developers and they have informed that this issue with SNI Apache memory consuming is unknown and was not reproduced on our test environment. You can fill detailed report http://forum.parallels.com/showthread.php?t=106113 and I will forward it to developers for investigation.
