Hello,
I've been running the 0.48argonaut on production for over a month
without any issue. and today, I suddenly lost one mon. Taking a look
into the syslog file, I see the following trace log. I just couldn't
see what's wrong from the trace log. However, this event created
a gigantic core file. Here's the size of the core file:
-rw------- 1 root root 16085647360 Aug 24 14:53 core
This happened while we were migrating data from our old storage
to the ceph. We are running about 20 processes, migrating data
into ceph, while there are about 30 more application processes
reading from and writing new data to it.
The following is from syslog:
