I am running 7.5.3.2 and have been experiencing SQL backup hangs ever since I 
upgraded to this version from 7.4.4 over 3 months ago.  I have seen hangs on 
log file (incr) backups of SQL and failures on differential and full backups 
with errors being i/o 995 errors.  We have not been able to isolate the issue 
as of yet, and EMC engineering has been looking into this for some time.  This 
does not happen with traditional file level backups for the same servers, only 
with SQL.  We can backup SQL to a local file and then backup that file with no 
errors.  We use the SQL Module.  I have tried lots of combinations of older SQL 
clients and older NW client versions and are now down to only a couple of 
clients that have this behavior having downgraded to SQL Module versions 5.0 
(for SQL 2005) or 5.1 (for SQL 2008).  This issue happens across all Microsoft 
OS versions, all SQL versions (2005 and 2008) and both 32 and 64 bit.

I know this isn't the same issue as yours, Dave, but I am curious if anyone 
else out there is seeing similar issues with backups hanging/erroring with i/o 
995.

Subject: [Networker] 7.6.1 - Savesets hang

We are running NetWorker 7.6.1 Server on Windows 2008 R2 Server.  This was 
installed a week ago last Friday.  Our old server was 7.5.2.

I know this has been discussed before and I've spent some time searching the 
archives and the EMC PowerLink Knowledge Base without much luck.

The problem is that on a somewhat random basis different savesets hang during 
backups, usually the bigger ones that take longer to backup.  I can often 
restart them by going onto the client and killing the save process but 
sometimes they hang again.  Our clients are a mixture of 7.5 and 7.6 which 
doesn't seem to make a difference to the problem.

Can anyone offer some help to me with the problem?

Thanks,
