it's related to ubuntu, but it may help to get an idea Thomas Von: "Mr. Courtney Creighton" <a...@dezignguy.com> An: assp-test@lists.sourceforge.net Datum: 19.11.2022 04:02 Betreff: [Assp-test] Unable to create UDP Socket errors Hi all, I'm running ASSP on CENTOS 7, with Perl 5.30.1. I recently upgraded from b22137 to b22318. Shortly afterwards, I'm seeing a new error from ASSP every few minutes: [Worker_10000] Error: DNS - unable to create any UDP socket to nameservers (1.1.1.10 111.111.111.22) * Not my actual DNS servers (I tested with Google public DNS and get the same result) As far as I can tell, mail is still working ok, and all ASSP features seem fine, even my DNSBL and URIBL are apparently still working. This has been rather difficult to troubleshoot, but `ss -tulpn` doesn't show anything excessive or unexpected as far as UDP usage. I did note that the CENTOS bind packages did see an update installed around this time as well. There was also a new kernel package installed. Perhaps there was a change in the behavior of that software that ASSP is having trouble dealing with? I'm looking for ideas for continuing to troubleshoot this, and also wondering if anyone else is seeing anything similar. -C
