Hello,
We are using Netbackup 7.6.0.2 with 2 media servers, all of them are on a windows 2008 R2 server.
Randomly, one of the media server lose his connection (always the same), and all the backups fails with error "disk media server is not active". For example, we had this problem at the beggining of this month, then nothing until the last week end and yesterday.
I've read that McAfee could cause this issue (relative to this technote https://support.symantec.com/en_US/article.TECH56658.html), but as I said the two media servers are the same, with the same version of McAfee, and the other one is OK. Moreover the process are in the exception list.
I've check the logs with vxlosview until 6 hours ago, and I've saw this :
"25/08/2015 08:17:15.914 [DA_Thread_Pool::CheckForHeartbeat] Found machine < asaus112 > not sending heartbeat
25/08/2015 08:17:15.914 [Error] V-144-1049 EMMServer generic error = Machine < asaus112 > not sending heartbeat, changing to OFFLINE"
Any idea of what I can check ?
Thanks !
