Re: [BackupPC-users] BackupPC_tarExtract exited with fail status 256

I'd like to get to the bottom of this.

First, please summarize your relevant $Conf Xfer settings for this host. Can you email the first several lines of the XferLOG file, in particular the lines that print which external commands it is running.

When the tar backup appears to be stalled, please do the following:

run ps auxww (options might vary based on which server OS you are running), and find the relevant backups processes: BackupPC_dump, BackupPC_tarExtract, and the corresponding ssh command that runs the remote tar.
run "strace -p PID" as root, for each number PID listed by ps above. Please send me the output.
wait a few mins, re-run the strace commands and see if the output is the same.

We should probably take these details off-list - just email them to me directly.

I ran into a similar error when I switched backups from rsync to tar to try to deal with a persistent timeout issue with one of my hosts. I’m still troubleshooting (in another thread on this list), but it’s starting to look like a network/interface issue to me.

Yeah, I searched and saw your post with no response. Quite honestly I didn't know how to reply specifically to your message so I mailed my own with your same title. So, sorry if I did things "wrong".

Oddly enough, it seems to only really happen to one or two of my client machines (my machine specifically being one of them).

I too am having this issue again with version 4.1.3 fresh from GIT. I did check the version of the file in /bin and it does show as being from 4.1.3.

Anything I can run to help you diagnose the problem?

I'm the original poster on this, and yours is the only response.

Meanwhile, I have backups running continuously here and they never, EVER complete. Every 24 hours, the current one gets killed with this same error and cleaned up, then a new one starts.
