[Gluster-devel] glusterd crashing

[Joseph Fernandes]

Hi Ajil,

Well few things,

1. Whenever you see a crash its better to send across the Backtrace(BT) using gdb and attach the log files (or share it via some cloud drive)

2. About the memory leak, What kind of tools are you using for profiling memory, valgrind ? if so please attach the valgrind reports.
   $> glusterd --xlator-option *.run-with-valgrind=yes 

3. Well I am not sure if glusterd uses any of the mempools as we do in client and brick processes, Atin can shed some light on this.
   Well In that case you can used the statedump mechanism check for mem-leaks check the glusterfs/doc/debugging/statedump.md

Hope this helps

~Joe
