Here is traces of all postfix processes at the time: pickup Z C212E180 48 522 520 523 (L-TLB) Call Trace: [do_exit+745/784] [sys_exit+14/16] [syscall_call+7/11] qmgr S F70FBF30 48 523 520 524 522 (NOTLB) Call Trace: [schedule_timeout+128/160] [process_timeout+0/16] [do_select+470/544] [sys_select+832/1152] [syscall_call+7/11] tlsmgr S F70F5F30 8944 524 520 523 (NOTLB) Call Trace: [schedule_timeout+128/160] [process_timeout+0/16] [do_select+470/544] [sys_select+832/1152] [syscall_call+7/11] master R F773F744 48 520 900 524 (NOTLB) Call Trace: [__write_lock_failed+9/32] [.text.lock.open+71/137] [unix_create+92/112] [sock_map_fd+12/304] [select_bits_free+10/16] [sys_socket+29/96] [sys_socket+48/96] [sys_socketcall+99/512] [syscall_call+7/11] Hope this will help someone to nail a problem It doesn't help. You need to find the backtrace of the other process holding the lock the AF_UNIX code wants as well, dumping just these few processes isn't enough. Franks a lot, David S.
