Hello,

when we started a deep scrub on our 0.56.2 cluster today, we saw a
massive memleak about 1 hour into the scrub. One OSD claimed over
53GByte within 10 minutes. We had to restart the OSD to keep the cluster
stable.

Another OSD is currently claiming about 27GByte and will be restarted
soon. All circumstantial evidence points to the deep scrub as the source
of the leak.

One affected node is running libc 2.15 (Ubuntu 12.04 LTS), the other one
is using libc 2.11.3 (Debian Squeeze). So it seems this is not a
libc-dependant issue.
