applied the patch and resident size increased only marginally over a 10 minute period. much better. ran through valgrind another 10 minutes, here's the report.
Only one definitely lost record was present, which should be fixed by the patch below. Some of the remaining leaks seem to be part of buffered messages not yet sent to destinations, but they were still reachable. Some reload tests would be appreciated (e.g. run syslog-ng and reload it a couple of times with your configuration and load), that might reveal some real leaks. --- orig/src/messages.c +++ mod/src/messages.c @@ -53,10 +53,12 @@ msg_send_internal_message(int prio, cons { LogMessage *m; - g_snprintf(buf, sizeof(buf), "<%d> syslog-ng[%d]: %s\n", prio, getpid(), msg); - m = log_msg_new(buf, strlen(buf), NULL, LP_INTERNAL | LP_LOCAL, NULL); if (G_LIKELY(internal_msg_queue)) - g_queue_push_tail(internal_msg_queue, m); + { + g_snprintf(buf, sizeof(buf), "<%d> syslog-ng[%d]: %s\n", prio, getpid(), msg); + m = log_msg_new(buf, strlen(buf), NULL, LP_INTERNAL | LP_LOCAL, NULL); + g_queue_push_tail(internal_msg_queue, m); + } } } -- Bazsi ------------------------------ _______________________________________________ syslog-ng maillist - syslog-ng@lists.balabit.hu https://lists.balabit.hu/mailman/listinfo/syslog-ng End of syslog-ng Digest, Vol 16, Issue 9 **************************************** The information transmitted (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is intended only for the person(s) or entity/entities to which it is addressed and may contain confidential and/or privileged material.
