FAQ

ERROR: Can't send to clamd: Broken pipe

grep -r LocalSocket /etc/clam*


Amavis not finding socket clamd.ctl

Means clamd is busy handling the queue after a powre failure or such, the socket won't be created before it's done.

 

INetMsg.SpamDomain-xxx

That's from sanesecurity.net

Milter (clmilter): local socket name /var/run/clamav/clmilter.sock unsafe

Usually means something like clamd not running.

 

LibClamAV Warning: [Bytecode JIT]: Bytecode run timed out, timeout flag set

Try --bytecode-timeout=120000

LibClamAV Warning: Bytecode run timed out in interpreter after 5000 opcodes

--bytecode-timeout=N

 

Ignoring mirror x.x.x.x (due to previous errors)

try removing mirrors.dat and daily.cvd

 

LibClamAV Error: CRITICAL: fmap() failed

haha yeah, good luck

 

Can't allocate memory ERROR

Some file too big?

 

Exclude dir

clamscan --exclude-dir='/foo/b.*r'

 

wildcards?

scan.conf: ExcludePath /foo/*/bar ?
