Good point. It also seems as well to change it in fork_sync_thread() and start_sync_thread(), though these are unlikely to be causing a problem. -- Horms H: http://www.vergenet.net/~horms/ W: http://www.valinux.co.jp/en/ Dean Manners notices that when an IPVS synchonisation daemons are started the system load slowly climbs up to 1. This seems to be related to the call to ssleep(1) (aka msleep(1000) in the main loop. Replacing this with a call to msleep_interruptable() seems to make the problem go away. Though I'm not sure that it is correct. This is the second edition of this patch, which replaces ssleep() in the main loop for both the master and backup threads, as well as some thread synchronisation code. The latter is just for thorougness as it shouldn't be causing any problems.
