We've observed these sorts of crashes (segfaults with stack having a rpc event happening), before when GlusterD is in the process of shutting down and exit() has been called. Since we don't correctly call fini() on xlators, rpcsvc continues accepting requests. But exit() would have cleaned up the resources that the rpc thread would have been using, leading to the thread segfaulting. > >> >> ~Atin >> >> On 02/10/2016 05:58 PM, Pranith Kumar Karampuri wrote: >>> >>> hi Atin, Kaushal, >>> Is this a known issue? >>> >>> (gdb) #1 0xbb789fb7 in __synclock_unlock (lock=0xbb1d4ac0) >>> (gdb) at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/libglusterfs/src/syncop.c:1056 >>> >>> #2 0xbb789ffd in synclock_unlock (lock=0xbb1d4ac0) >>> at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/libglusterfs/src/syncop.c:1071 >>> >>> #3 0xb9b803ff in glusterd_big_locked_notify (rpc=0xb8bc2070, >>> mydata=0xb950efa0, event=RPC_CLNT_DISCONNECT, data=0x0, >>> notify_fn=0xb9b8ec28 <__glusterd_brick_rpc_notify>) >>> at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/xlators/mgmt/glusterd/src/glusterd-handler.c:72 >>> >>> #4 0xb9b8f0d7 in glusterd_brick_rpc_notify (rpc=0xb8bc2070, >>> mydata=0xb950efa0, event=RPC_CLNT_DISCONNECT, data=0x0) >>> at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/xlators/mgmt/glusterd/src/glusterd-handler.c:4993 >>> >>> #5 0xbb708c22 in rpc_clnt_notify (trans=0xb8bc8030, mydata=0xb8bc2090, >>> event=RPC_TRANSPORT_DISCONNECT, data=0xb8bc8030) >>> at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/rpc/rpc-lib/src/rpc-clnt >>> at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/rpc/rpc-lib/src/rpc-clnIllegal >>> process-id: >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/libglusterfs/src/syncop.c:1056. >>> >>> (gdb) #2 0xbb789ffd in synclock_unlock (lock=0xbb1d4ac0) >>> (gdb) at >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/libglusterfs/src/syncop.c:1071 >>> >>> Illegal process-id: >>> >>> /home/jenkins/root/workspace/rackspace-netbsd7-regression-triggered/libglusterfs/src/syncop.c:1071. >>> >>> (gdb) #3 0xb9b803ff in glusterd_big_locked_notify (rpc=0xb8bc2070, >>> mydata=0xb950efa0, event=RPC_CLNT_DISCONNECT, data=0x0, >>> (gdb) notify_fn=0xb9b8ec28 <__glusterd_brick_rpc_notify>) >>> Undefined command: "notify_fn".
