Hi.

I'm trying to investigate the cause of some weird problem where OpenDKIM stuck after some time and as the result, I will have a huge mail queue.

The version of the opendkim is:

opendkim: OpenDKIM Filter v2.11.0 Compiled with OpenSSL 1.1.1g FIPS 21 Apr 2020

OS: Centos 8.

The only thing which I mentioned in the message on one of the system log such as:

OpenDKIM Filter: accept() returned invalid socket (Numerical result out of range), try again

Does anyone have a clue what might be a cause for this problem?

https://sourceforge.net/p/opendkim/support-requests/41/ had a similar problem. Sounds like the various forked processes stopped executing or were so slow there were hundreds of processes in parallel making very slow progress. Did you try tracing any of the running processes using 'ltrace -S' or similar to see if any were progressing, or if they were deadlocked in some way?

I'm facing this issue too since I started using 2.11.0. I've used 2.10.3 for years in the same environment and never had this problem. I upgraded from version 2.10.3 to 2.11.0 in last April and immediately started having this problem. libmilter was compiled with SM_CONF_POLL. Thx.

This looks like it's a dupllcate of #149 -- can you please have a look at that one and see if you see anything different (or similar?).

You're on CentOS 8 -- how did you install OpenDKIM? Manual build or package?
