After upgrade MailScanner to 4.68 just hangs at extracting attachments

[ram]

I recently upgraded to MailScanner 4.68-8.1 from 4.5
Now After upgrading the conf file I can see no mails being scanned at
all 

If I start MailScanner in debug mode it just hangs at "Trying to
setlogsock(unix)" 

Can someone tell me what has gone wrong  please 



MailScanner --lint  output

Checking version numbers...
Version number in MailScanner.conf (4.68.8) is correct.

Unrar is not installed, it should be in .
This is required for RAR archives to be read to check
filenames and filetypes. Virus scanning is not affected.

If any of your virus scanners (clamavmodule,f-prot)
are not listed there, you should check that they are installed correctly
and that MailScanner is finding them correctly via its
virus.scanners.conf.
