Hi All, Spun up a new RHEL 9 VM and installed below RPMs for 3.2.8: freeradius-utils-3.2.8-1.el9.x86_64.rpm freeradius-config-3.2.8-1.el9.x86_64.rpm freeradius-3.2.8-1.el9.x86_64.rpm After installation, no configuration changes were made (kept at default). We then ran "systemctl start radiusd" and saw the below error via "journalctl -u radiusd": Aug 21 23:58:45 vm-68a7af574aa13c7161eb42f4.us-east-1.compute.is.apple.com radiusd[24178]: Compiling Post-Auth-Type REJECT for attr Post-Auth-Type Aug 21 23:58:45 vm-68a7af574aa13c7161eb42f4.us-east-1.compute.is.apple.com radiusd[24178]: /etc/raddb/policy.d/filter[31]: Invalid regular expression: Aug 21 23:58:45 vm-68a7af574aa13c7161eb42f4.us-east-1.compute.is.apple.com radiusd[24178]: /etc/raddb/policy.d/filter[31]: Aug 21 23:58:45 vm-68a7af574aa13c7161eb42f4.us-east-1.compute.is.apple.com radiusd[24178]: /etc/raddb/policy.d/filter[31]: ^ Pattern JIT failed: no more memory Aug 21 23:58:45 vm-68a7af574aa13c7161eb42f4.us-east-1.compute.is.apple.com systemd[1]: radiusd.service: Control process exited, code=exited, status=1/FAILURE Aug 21 23:58:45 vm-68a7af574aa13c7161eb42f4.us-east-1.compute.is.apple.com systemd[1]: radiusd.service: Failed with result 'exit-code'.

We also tried upgrading an existing RHEL 8 VM running 3.2.7 (used el8 RPMs) with our custom configs and encountered the same error. If we run radiusd in debug mode, it appears to start up without issue, so issue is only when trying to start via systemd. We have plenty of memory/RAM allocated to both VMs. Many thanks. Kind regards, Cyrus Humphreville
