The corresponding code in Postfix which triggers this is (choice of 3 files in src/master are all possibilities which all have much the same code) /* * The event loop, at last. */ while (var_use_limit == 0 || use_count < var_use_limit || client_count > 0) { if (multi_server_lock != 0) { watchdog_stop(watchdog); if (myflock(vstream_fileno(multi_server_lock), INTERNAL_LOCK, MYFLOCK_OP_EXCLUSIVE) < 0) msg_fatal("select lock: %m"); } watchdog_start(watchdog); delay = loop ? loop(multi_server_name, multi_server_argv) : -1; event_loop(delay); } multi_server_exit(); } Now I'm not convinced this is an application problem, because I'm only seeing this after running up kernel 2.6.23-rc6-mm1 or 2.6.23-rc7-mm1 and with NO changes to the application itself. Using the same application binaries it does not occur with 2.6.22 mainline. [I didn't get a lot of testing with the -mm release prior to that unfortunately due to some other breakage.] Is there anything new in the last two or so -mm kernels which could have caused this? I've put my .config up at http://www.reub.net/files/kernel/2.6.23-rc7-mm1.config Thanks, Reuben - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
