Error code 25s logged - very strange behaviour
We have a very starange issue that happens in our environment. We use version 7.7.3 writing to MSDP dedup poools.
Every day say day 1 at 13:00 we will get a cluster of error code 25s on several clients and several dedup pools it can be any job - we would get say between 20 and 50 code 25 errors. These code 25 errors only ever happen on Application backups - SQL, Rman Oracle and SAP. UNIX OS Windows OS and VMware backups are never ever affected.
On day 2 the same will happen but this time at 13:30, day 3 at 14:01, day 4 at 14:30 etc, always the next day but +30 minutes (give or take a few minutes) we have engaged support and are working through things but so far have drawn a blank. The clients are all on 7.7.3.
If anyone has any ideas on this I would be most grateful as we are not making much headway at all - if the jobs are re run they will all complete. But every day we are having to deal with many auto tickets due to these database application type backup failures.
Many thanks
