Virus scanning hanging?

[Gottschalk, David]

Yeah, I saw the files in the actual mqueue.in folder. I tried to do a strace, but for some reason strace isn't working on these machines right now.

I turned off Dangerous content filtering, and the message went through. I'm still curious though about what happened, and worried it might happen again.

I wish I could do a strace, then I could have seen what it was trying to do while taking up 98% of the CPU.

Nah.
Might be that they are some very strange files? Zip-bombs come to
mind.... Or your file command misbehaving?
You can probably "catch" them in the act in the MailScanner incoming
directory ... And check that that hasn't run full or something like
that.... The files are in subdirectories like
/var/spool/MailScanner/incoming/<PID of worker>/<queue ID>/<the actual
files> (IIRC:-).
