[Gluster-infra] [Gluster-devel] bug-1432542-mpx-restart-crash.t failing

[Poornima Gurusiddaiah]

The same test case is failing for my patch as well [1]. I requested for a
regression system and tried to reproduce it.
>From my analysis, the brick process (mutiplexed) is consuming a lot of
memory, and is being OOM killed. The regression has 1GB ram and the process
is consuming more than 1GB. 1GB for 120 bricks is acceptable considering
there is 1000 threads in that brick process.
Ways to fix:
- Increase the regression system RAM size OR
- Decrease the number of volumes in the test case.

But what is strange is why the test passes sometimes for some patches.
There could be some bug/? in memory consumption.

Poornima
