Hallo, Tom, Du meintest am 09.06.11: > I think, that if squid "realize" that something is wrong, it shutdown > (or even dies) with sending the mail to the "cache_mgr". Why should squid send mails when it dies? "before I die please give me 10 minutes to inform all my relatives!" Perhaps you need another job which only watches the squid PID. Viele Gruesse! Helmut
