It still indicates a timing issue. A TTL expired because the server cannot keep up, power saving mode turned off PHY ( which could be a switch, rather than server or client machine), anything that causes a packet drop. Also, another possibility is 5. The limit, recent, or some other iptables module is causing an unexpected packet drop under load. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
