I have been having this problem with dump for several months now, and I was
hoping for it to fix itself with newer versions, but so far it hasn't so I am
posting it again.

I have a backup script that uses dump to backup my filesystems. I was using it
fine, until several months ago, when it stopped working. The problem is that
while dumping, several dump threads (childs of a dump thread in unix_select) go
into pause, and then the whole thing hangs.

Here is the output of "ps axfwww":

...

 2697 pts/5    S      0:00  \_ su -
 2745 pts/5    S      0:01      \_ -bash
 8367 pts/5    S      0:00          \_ /bin/bash /usr/local/bin/backup full
 8534 pts/5    S      0:10              \_ dump -0 -u -z -M -s 27306 -f
/backup/current/home.full. /home
 8543 pts/5    S      0:05                  \_ dump -0 -u -z -M -s 27306 -f
/backup/current/home.full. /home
 8544 pts/5    S      0:33                      \_ dump -0 -u -z -M -s 27306 -f
/backup/current/home.full. /home
 8545 pts/5    S      0:33                      \_ dump -0 -u -z -M -s 27306 -f
/backup/current/home.full. /home
 8546 pts/5    S      0:33                      \_ dump -0 -u -z -M -s 27306 -f
/backup/current/home.full. /home

...

And here is the output of "ps axl":

-z -M -s 27306 -f /backup/current/home.full. /home

Is anyone else using dump and having a similar problem? I don't know what else
to do to debug this. Any help?

Thanks.
