** [tickets:#1705] log: miss mutex protection for common resource in log agent**
**Status:** accepted
**Milestone:** 5.0.FC
**Created:** Fri Mar 18, 2016 10:11 AM UTC by Vu Minh Nguyen

There is an race condition between two threads accessing to common resource
`lga_cb.client_list`:
1) The client thead which is in context calling to saLogFinalize(), trying
to delete `lga_cb.client_list` resource.
The code flow something looks like:
> saLogFinalize()->lga_destroy()->lga_hdl_list_del(): delete lga_cb.client_list
2) The recovery thread (recovery2_thread) which is referring to above
common resource.
The code flow something looks like:
> recovery2_thread()->recover_one_client(): referring to the resource
So, log client will get the coredump if the thread #1 goes first, then thread
#2 refering to the resource.
