It seems as if your system doesn't have enough free memory. What's the output of

free

?

Looks like you're running OOM

when a new mail is incomming, it sets amavisd to work, that wants to fork some processes, but it can't, because it runs out of memory.

I've increase memory on my mail server virtual machine and now it work fine ^^.

Thank you for your help Till, Falko and Mark
