Hello

Since upgrading from 0.97 to 0.97.3 it's been less then satisfying on a
fedora c3 server, I have a 7.3 server without issues

Every time (it seems) i run freshclam on the FC3 machine it wants to
redownload the main.cvd database over and over, not sure why as that
database doesn't appear to change, but it keeps giving me messages such as
Malformed database and Can't verify database integrity. Happens after it
was successful once before.

Note: this sporadically happens with daily.cvd and occasionally bytecode.cvd

Every once in a while the download works as expected, but then it starts
over again with the same issues.

I've had to turn off freshclam and just wget databases to get clamd to
function at all without barking. This is also not 100%

After freshclam update
clamd log:

configure command option --disable-zlib-vcheck the actual version is 1.2.1

bzip2 on problem and working machine is at 1.0.2, not sure this is an
issue as one works the other doesn't (also this didn't seem to be a
problem until the upgrade to 97.3)



Any Ideas?
