Hi Patrick/Daniel
sorry for the late reply
0.6 TB of data are written each day and are backed up on the shared folder.
the shared folder is part of a backup solution which I don't have admin access for (it's managed by different team who won't change anything from their side)
during certain periods the machine becomes unresponsive even if I perform snmpwalk locally I get timeout.
Regards,
Samir

0.6 TB every day? Wow! That’s quite some data. Or you mean 0.6 TB over
time?

Is the problem speed of NFS or size of the open files?

If the servers are busy waiting for network, then move from NFS
otherwise, rotate the logs.
