[clamav-users] Freshclam failing to get update

[Simon Banton]

Hi,

Is there anything about ClamAV v0.97.3 that would mean it's suddenly unable
to fetch the daily updates via freshclam? I know it's an old version, but
this is on a very old box running Centos 4 so upgrading isn't practical at
the moment (for, you know, *reasons*).

Suddenly started seeing this whenever freshclam tries to run:

Feb 11 13:07:16 ptah freshclam[24470]: Trying again in 5 secs...

This started to happen yesterday after years of trouble free operation.
Nothing on my box's configuration has changed between freshclam working and
it not working.

Any pointers as to a possible cause would be most welcome.

Cheers
Simon
