Re: [Bacula-users] Director's comm line to SD dropped

Hi. I keep getting this error on one of my servers.

A few words about the setup:

The director is running under Ubuntu 12.04 LTS in a virtual machine on a very lightly loaded Xeon X3 with SSDs.

The FD and SD are both running on a QNAP NAS box. I hand-built a bacula package for the QNAP. All are running 5.2.12.

I have two identical QNAP NAS boxes, running the identical bacula package, and one works perfectly and has been extensively tested. The only difference is that one is connected to the director via a VPN (over Comcast Internet) and one is on the same LAN.

The one on the remote QNAP will sometimes work for days and then sometimes only for a few hours. Restarting the SD will always make it work for a while. The log looks like this:

Thanks in advance for any light you can shed on this.

Hi Jeff,

You should read this : http://wiki.bacula.org/doku.php?id=faq#my_backup_starts_but_dies_after_a_while_with_connection_reset_by_peer_error
Especially the part talking about keepalive (considering you are using a VPN).
