[Gluster-users] Glusterd proccess hangs on reboot

My guess is there is a corruption in vol list or peer list which has lead
glusterd to get into a infinite loop of traversing a peer/volume list and
CPU to hog up. Again this is a guess and I've not got a chance to take a
detail look at the logs and the strace output.

I believe if you get to reboot the node again the problem will disappear.

[Gluster-users] Glusterd proccess hangs on reboot

I reboot multiple times, also I destroyed the gluster configuration
and recreate multiple times. The behavior is same.

[Gluster-users] Glusterd proccess hangs on reboot

Same thing happens with 3.12.rc0. This time perf top shows hanging in
libglusterfs.so and below is the glusterd logs, which are different
from 3.10.
With 3.10.5, after 60-70 minutes CPU usage becomes normal and we see
brick processes come online and system starts to answer commands like
"gluster peer status"..
