The process is getting crashed during call ios_bump_stats in cbk code path.
After checked the code it seems the process is getting crashed because the
ios_stat_head list is destroyed by the function ios_destroy_top_stats
without taking a list mutex while receive a clear profile event from the
client. If at the same time a process is trying to access the list
it can be crash.
Solution: Destroy the ios_stat under the list mutex.

Testing
GlusterFS source contains some functional tests under tests/ directory. All
these tests are run against every patch submitted for review. If you want your
patch to be tested, please add a .t test file as part of your patch submission.
You can also submit a patch to only add a .t file for the test case you are
aware of.
To run these tests, on your test-machine, just run ./run-tests.sh. Don't run
this on a machine where you have 'production' glusterfs is running, as it would
blindly kill all gluster processes in each runs.
If you are sending a patch, and want to validate one or few specific tests, then run a single test by running the below command.
bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t
You can also use prove tool if available in your machine, as follows.
bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
