Apabila email tidak sampai ke mailbox dan log MailScanner (maillog) terdapat ralat berikut:
Oct 23 22:32:06 email MailScanner[21705]: Virus and Content Scanning: Starting
Oct 23 22:32:06 email MailScanner[21705]: Clamd::ERROR:: COULD NOT CONNECT TO CLAMD, RECOMMEND RESTARTING DAEMON :: .
Oct 23 22:32:07 email MailScanner[21705]: Virus Scanning: Clamd found 1 infections
Oct 23 22:32:07 email MailScanner[21705]: Virus Scanning: No virus scanners worked, so message batch was abandoned and re-tried!
Kemudian cuba restart clamd, ralat berikut pula muncul
