So *all* the parent directories (/var, /var/log, and /var/log/clamav)
are world-readable?

The permissions on /var/log/clamav/clamd.log don't really matter - it
could have permissions  ({read,writ,execut}able by nobody), and one
could still stat it correctly.

The permissions of clamd.log are ignored when stat(2)ing it.  One can
stat a `chmod 0' file.  What matters is execute permission on the four
directories leading to it.

Also, don't trust the error message if it seems incorrect.  Track down
the cron job and edit it to use strace(1) to learn what system calls
fail and how.

I have to think this is something you're triggering yourself.  ClamAV 
doesn't seem to ship with any cron jobs.  (See "pacman -Ql clamav | grep 
cron")  So this must be either a cron job you've added yourself, or some 
old one that's left hanging around.


As far as the clamd log file, I think it's normal to be empty if you're 
not running clam as a daemon.  That's how mine is:


$ ls -l /var/log/clamav/clamd.log
-rw-r--r-- 1 clamav clamav 0 May  5  2013 /var/log/clamav/clamd.log

Only other remaining explanations I could offer are:

* The drive that /var/log/clamav is on is damaged and unreadable.  (See 
if you see any errors in either dmesg or /var/log/messages)


* You have a permissions issue on either /var/log/clamav, /var/log, or 
/var, whereby the user running the cronjob doesn't have read or execute 
permissions to one of those directories.

Well, that what I was investigating, but the log is world readable, so that
can't be the case -- and the only permissions needed to stat a file is read
permission.

Also suspect is the log file is empty and 3 years old, so I'm not sure what is
going on with it, but I do know I never got an error about it until 9/15.

Could be a permissions issue. If a user cannot access /example/ then
it cannot see if /example/test exists and will give a no such file or
directory error.

Archdevs,

  Is this a new bug or config issue? Beginning 9/15, I receive a new cron error:

error: stat of /var/log/clamav/clamd.log failed: No such file or directory

  But the file is there:

$ l /var/log/clamav/clamd.log
-rw-r--r-- 1 clamav clamav 0 Aug 30  2015 /var/log/clamav/clamd.log
