I installed a eval Linuxshield 1.5.1 on OES2 and started it with no errors. Its monitoring web page show it running properly and the number of files scanned was increasing.

Suddenly all the users started complaining they can't access their files on the network drive. We can see the files listing but whether is excel, word or ordinary text files, all of them won't open.

Killing the Linuxshield nails service immediately resolved the issue.

It seems when Linuxshield was running, all files on the NSS volumes were unaccessible but it was not flagging them as viruses. Files on local reiserfs volumes were strangely not affected.

Appreciate if you have any ideas on what went wrong?
