Hello,
tested on 6.2 and on 6.2-current. relayctl poll command invoked even
as ordinary user may segfault one of relayd child processes hence
failing whole relayd.
The process which fails is "relayd: hce (relayd)" and it fails with
following crash backtrace:
Program received signal SIGSEGV, Segmentation fault.

The process to duplicate this issue is:
- start relayd as root with -dvv
- ps uxa|grep relayd|grep hce
- gdb /usr/sbin/relayd <process id above>
on another console:
- relayctl poll
In gdb, you should see the crash.
