Stalled backups or Engine service not responding
I was using BE 12.5D (on 2008R2) for a few years with very few issues. I upgraded the software to 2012 SP4 and after getting used to the differences settled down to about 2 weeks of no issues. Then without making any changes to the server or software, my backups started failing. I tried resolving the problem, which most of the time was "The Backup Exec job engine system service is not responding." The server wwould also restart for no apparent reason during a the backups so some of the failures were due to the backup not being able to continue from where they were interupted. I couldn't find anything in the Event Viewer to point to the problem, so I decided to do a clean install. I formatted the server, reinstalled the OS, updated it and then installed BE 2012, updated that. I then reinstalled the agents on all the servers too and restarted them to make double sure.
I created a Once-off backup of my Exchange server - Hyper V, 2008R2, Exch 2010 Std SP3. The backup got to about 3gb in size and then you could just watch the speed casually drop every 2 seconds or so, even though the size stayed at 3gb. The BE server would either restart or the job would fail with the "not responding" error.
I created a Once-off backup of a File Server - Physical, 2008R2, using DFS. The backup would initiate and then after about 10mins would stall and the same error "not responding".
I need a "fresh set of eyes" to help me here to see what I am missing. I have looked at this page:
without any luck.
My BE server specs are:
HP DL 380 G6, 6GB RAM, 2008R2 ENT, roles: Domain Controller, DNS
