Job status not getting updated in Activity Monitor

Hi All

we are having a location where the job status is not getting updated in Activity Monitor.Jobs are stuck as writing/mounting even when the Job detailed status exit with 0.

Master Server :Netbackup-solaris10       7.5.0.4

Media server : Netbackup-Linux 2.6.18   7.5.0.4

The Media server is in a different domain and communicates with master over the WAN.I heard theres a known issue with NB 7.5.0.5 but we are on

NB 7.5.0.4.
