Greetings everyone;

I have a case open with EMC with regard to this problem where a hung client
will hang the savegroup that contains that client. I have this case open for
my NetWorker 7.4.4 server on Red Hat Linux AS 4.5, but I also have the same
problem with NetWorker 7.4.1 server on Solaris 10.

One of the things they had me do from EMC on my Linux server was

 save -v -D9 -g grp_name -c client_name

We did that for one client in a group that was hanging after I manually
stopped the group from the NCM GUI.

The problem just happened on my Solaris NetWorker server, so I tried a
similar thing where I logged onto that NetWorker server and for every client
in the failed group, I issued a command along the lines of

 save -v -D9 -g grp_name -c client_name1 -c client_name2 -c client_nameN

I included all nine clients in the group. The scheduled backup today is an
incremental for that group. The schedule is controlled by the group. The
backup worked. Then I went into the NMC GUI and I started the group that
way. Again, it worked.

What I am wondering is why it worked. Why did running the backup from the
NetWorker server manually fix the problem?

Actually, in this case, the group in question didn't hang, it just died and
all nine clients registered a failed backup in the resulting savegroup
report.

EMC and I have been trying to troubleshoot this issue on my Linux NetWorker
server (which backs up much more important data then our Solaris NetWorker
server), but since we tried that stunt with manually backing up one of the
stuck groups, the problem hasn't occurred again so we are waiting for it to
happen again so we can collect some debugging info.
