glusterd: glusterd is crashed at the time of stop volume
Problem: glusterd is crashed at the time of stop volume due to
overflow of pidfile array after build rpm with default options.
Solution: To avoid the crash update the pidfile array size.
Test: To test the patch followed below procedure
1) Setup 1*2 environment and start the volume
2) Stop the volume
Before apply the patch glusterd is crashed.
Note: The crash is happened only after build rpm with rpmbuild -ba
<spec> because _FORTIFY_SOURCE is enabled. This option tries to
figure out possible overflow scenarios like the bug here and
crash the process.
