If I look through my logs, every few days or so I see a few messages that look like:
lrmd[4144]: 2008/06/07_01:27:03 WARN: G_SIG_dispatch: Dispatch function for SIGCHLD was delayed 1000 ms (> 100 ms) before being called (GSource: 0x16e2e9b8 ) lrmd[4144]: 2008/06/07_01:27:03 info: G_SIG_dispatch: started at 465607845 should have started at 465607745 lrmd[4144]: 2008/06/07_12:44:01 WARN: G_SIG_dispatch: Dispatch function for SIGCHLD was delayed 1000 ms (> 100 ms) before being called (GSource: 0x16e2e9b8 ) lrmd[4144]: 2008/06/07_12:44:01 info: G_SIG_dispatch: started at 469668996 should have started at 469668896 I asked on the irc channel, and someone commented that they are probably nothing to worry about. However, today I had a node failure on or about the same time as these dispatch messages. The timeout for the IP Address is 5 seconds, and actually I and another guy were working in the database at the time of failure - using the VIP. lrmd[4144]: 2008/06/09_19:03:25 WARN: G_SIG_dispatch: Dispatch function for SIGCHLD was delayed 1000 ms (> 100 ms) before being called (GSource: 0x16e2e9b8 ) lrmd[4144]: 2008/06/09_19:03:25 info: G_SIG_dispatch: started at 489221947 should have started at 489221847 lrmd[4144]: 2008/06/09_19:38:21 WARN: ip_mysql:monitor process (PID 27595) timed out (try 1).

Are the events related, or is the dispatch error a complete red herring in this case? _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
