Summary0013998: Freeradius random segment fault crash

Kernel: 3.10.0-693.2.2.el7.x86_64
radiusd: FreeRADIUS Version 3.0.13, for host x86_64-redhat-linux-gnu, built on Aug 23 2017 at 15:18:22

Recently upgraded the OS which included an update to freeradius and noticed that it is crashing at random times. Dont see anything interesting in the logs. $ radiusd -X starts normally. But do see segfaults in $ dmesg

Saw this post with same issue as us.
ldap module is enabled

Had submitted issue to freeradius-users mailing list and they suggested to try the latest 3.0.X-HEAD release which is 3.0.15. Opted to try the latest stable release from
 Installed that and noticed that their systemd service file has 'Restart' and 'RestartSec' lines. This commit was implemented back in 2015.
The 3.0.15 freeradius also crashed but would restart normally because of the service file.

Historically with freeradius we have seen that it crashes or it has memory leaks and with upgrades that solves itself. This latest update has been the most impacting because it crashes constantly. So im wondering why is it crashing and why does the centos rpm repo file not have those 'Restart' 'RestartSec' lines? Would be nice not to depend on those lines.

As a workaround i added the restart lines to the radiusd service.

We have 3 radius servers displaying the same behavior. Anything else to try?

Any input is appreciated!

Steps To Reproduce1. yum upgrade
2. updated raddb config files with any rpmnew files created.
3. reboot server
4. all services start but radiusd crashes randomly

Also did a clean OS build from scratch and same results.

Is this still an issue for you (or at least is this still an issue with the packaged FreeRADIUS)?

If so, would it be possible for you tell me a little more about your scenario in order for me to replicate the issue?

I'd be interested in things like number of clients, number of requests per client, type (auth, acct, etc) and ratio of requests (1x auth + 2x acct per connection, auth-only, etc), number of requests per timeframe (1000/hr, 10million/day, etc).
