On a production system with a large throughput, which has been working without issue for many years, we are now seeing OpenDKIM segfaults (about once per two weeks) for which the reason is unclear. # yum list installed | grep opendkim libopendkim.x86_64 2.11.0-0.1.el7 @epel opendkim.x86_64 2.11.0-0.1.el7 @epel opendkim[22317]: segfault at 290 ip 0000000000409dbc sp 00007fa4bbffec50 error 4 in opendkim[400000+25000] Reproducible: Sometimes Steps to Reproduce: 1. Leave OpenDKIM service running, signing and receiving signed and unsigned mail Actual Results: segfault Expected Results: Service works without issue and logs any issues in the logs We've worked around the issue by simply setting the systemd service to restart on failiure and this seems to work fine. However obviously the service shouldn't segfault. I am not dismissing the possibility that there is some other issue in the email system that is causing the input to be incorrect somehow, but the program should log that instead of segfaulting. I've installed abrt as per https://access.redhat.com/solutions/56021 and will provide the core dump / trace when I have one.
EPEL 7 entered end-of-life (EOL) status on 2024-06-30.\n\nEPEL 7 is no longer maintained, which means that it\nwill not receive any further security or bug fix updates.\n As a result we are closing this bug.
It's worth noting that the version of the OS is irrelevant here, because the OpenDKIM software is the same in each operating system. But sure close it. Your loss.
