[OVZ] 042stab107.x kernels swap-happy?

[Geek]

Just wondering if anybody else is seeing larger than average kswapd utilization on the CPU / larger than normal swap consumption on the host in the recent OpenVZ kernels (107.x/108.x)?

Checking bugzilla too... occurring on two machines now that had perfectly normal utilization in prior kernels. 

Thanks,

John

Seen it in VMs that I have purchased. Swaps everything to Swap, and has 0 mbs ram usage. Really funny actually.

I haven't seen anything like this, but i use swappiness=0 so maybe that helps.

I wonder if they messed around with vswap.  People are reporting that vswap is being used on containers when --swappages 0:0 is set on the node for certain CTs.  Hmph.

I've noticed it in containers with recent kernels...
