Re: [Tier-users] Stability question...

Hi everyone,

It looks like my initial stability issues was with CloudLinux 7 (which is a branch of CE7). I've switched back to CloudLinux 6 which has been stable. I've ran into one other issue though. Running for a few days with the -B option has caused a basically idle system to use over 10GB of RAM. Slabtop shows the following info:

  OBJS ACTIVE  USE OBJ SIZE  SLABS OBJ/SLAB CACHE SIZE NAME
20303820 20303816  99%    0.25K 1353588       15   5414352K biovec-16
20303940 20303877  99%    0.19K 1015197       20   4060788K bio-0

Does this mean there is a possible memory leak in the new block io method for the 2.6.32 kernels? Or is using 10GB on block io buffers expected and can be purged if the system runs out of memory?

Switching to the older vfs method has not caused any excessive memory usage so I'm running in that mode for now.
