Hello all,
I am having a problem with rdiff-backup, has anyone seen this before?
Any debugging info would be appreciated!
I am trying to back up a FreeBSD 4.11 box to a new FreeBSD 6.0 host. The
initial run (about 25GB) seems to stop at a random moment (on a
different file - sometimes after a few minutes, sometimes after an hour
or so).
The traceback is fairly long but it seems to boil down to "select: Bad
file descriptor" at the server end... How would I debug this?
Cheers!
walter
