rpc_clnt_connection_cleanup() called during unref() does saved_frames_destroy which in turn does a ref() and unref() on the rpc_clnt. Because of this behavior rpc_clnt gets destroyed again causing memory corruption. I will send a patch which will do rpc_clnt_connection_cleanup() before unref()ing the rpc_clnt which will prevent the mem corruptuon/crash but still a kludgy approach. *** Bug 804489 has been marked as a duplicate of this bug. *** CHANGE: http://review.gluster.com/2979 (rpc-clnt: separate out connection_cleanup() from destroy()) merged in master by Vijay Bellur (vijay) |
