Subject: [BUG?] OOM with large cache....(x86_64, 2.6.24-rc3-git1, nohz)
Hi,
I have had this before and sent a mail about it.
It seems like the diskcache is still in use and is never shrunk. This
happened with a odd load though, trackerd started indexing a bit late
and the other workload which is a large bittorrent seed/download.
The bittorrent app is the one that drives up the diskcache.
I don't think that trackerd was triggering it, i actually upgraded
kernel since it kept happening on 2.6.23...
I really don't know what other information i can provide.
free from now (some hours later)
vmstat from now ^
and the dmesg log.
Ideas? Comments?
