Just want to give an update if anyone is interested. Seems like the problem was on our router's end. We have set all mtus to enable jumbo frames @ 9000 but the opnsense router doesnt reflect on the terminal side. It shows an mtu of 9000 only on the webgui. Solved when i upgraded the router to 17.7, previous version which also has the same bug is 16.7 Hope this helps Also a client hangs when the systemfiles also hangs -- You received this message because you are subscribed to the Google Groups "bareos-users" group.
