Hi Mark,

Which pcre2 version are you using?

Regards,
Micah

Hi James,

Glad that seems to have helped.

Al and others are correct that the distro should be updated to use pcre2, but I'm not convinced that's the root of the problem. We're seeing the issue with that signature despite already using pcre2 in our build.

Although I complete support what Mark has recommended, I would caution that there could easily be a future signature that will cause this same issue if the root cause of not upgrading to pcre2 is not accomplished, and figuring out what signature that is won’t be easy.

Try excluding Email.Exploit.Efail-6641027-1 from the main ClamAV set.

Thanks Mark. After over 12 hours clamd is still up and running. Looks like that sig was causing the problem.

James.
