These are different messages from those you reported originally (which all mentioned client:10.32.12.18:9101 with time 12:27 and 12:28). They are almost certainly caused by a port scan though, so nothing to worry about. Nevertheless, I would report these latest messages as a bug, because it looks like Bacula has erroneously associated them with JobId 113, which possibly caused the spurious "Backup OK -- with warnings". It looks like a double error: something has detected the packet size problems and reported this back to getmsg.c in a malformed way. __Martin ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
