ERR - Cannot write to STDOUT. Errno = 110: Connection timed out
Hi All;
My backup system is running on 7.7.2 ( master server running on cluster, 9 media servers), they are linux servers. Media servers (1, 2, 3) are configured with tape drive and Data Domain. Media server 4 is configured with tape drive. I have a issue when I tried to backup media server 4 & 9 to data domain even I tried backup them with tape drive of media server 1 but if I backed up media server 4 with tape drive itself then it worked well. I tried to increase CLIENT_READ_TIMEOUT to 3600 on master & media server but it keeps failing.
I created bpbkar log , it shows :

Thank you.
Hi All;
Finally I found the root cause and resolved the issue. It is MTU issue. Thank you everyone.
