Description

ceph: 0.25.2
client: 2.6.38.1-2
default setups, 2 nodes 3 osd each

while (copying) writing a lot of files (e.g., ~600millions of sized 2kb = 12GB)
the ceph client crashes with an error message below (copied for about 10 minutes)

Unsure whether it is due to the pgs being full?
attached file has the log.

Thanks a lot
