Hi Steve
Note it would be nice if clamd said which db it did not like ..
I reckon the start of the problem is "Database reload failed, keeping
the previous instance" when there is no previous instance.
Mon May 22 13:04:40 2023 -> Reading databases from /var/lib/clamav/
Mon May 22 13:05:01 2023 -> ERROR: reload_th: Database load failed:

Lots more of the above snipped
Note a /tmp/clamav-*** is created for each connection containing
whatever was submitted till max files open limit is reached.
Then this starts

Hi
I have found that 1.0.1 and 0.103.8 both behave badly if they find a
malformed db. Agreed freshclam checks out the clamav/cisco db's.
I have yet to determine what unofficial db caused the failure. They
should all have been verified before being placed in /var/lib/clamav/
How are you downloading the 3rd party sigs...
This script checks integrity... before copying to live folder...
https://github.com/extremeshok/clamav-unofficial-sigs
I check db integrity before uploading to mirrors.
Please email me off list with some logs....
Cheers,
Steve
