Unable to write files to network
Here is the situation Protection Engine has been implemented, two PE servers for EMC VNX, using ICAP protocol.
Turned virus scanning on out of hours approx 20:00 at night, the next day it was ok until around 10:00am when users were no longer able to save files to CIFS shares on the NAS. This was from applications like Office so updating an existing Word document would not be saved, and even when trying to create a new file, such as a text file.
PE servers are set to scan and repair files only, there hasn't been any major performance issues on the PE servers, they've scanned just over 200K files between them. In order to prevent issues to the users, virus scanning on the VNX has been turned off. Not blocking any access to containers just logging, same for files, URL and Mail scanning is not turned on.
Whilst it was working for around 14hours, now if we enable virus scanning on the VNX it immediately prevents writing to the CIFS shares.
Any advice appreciated.
