Hello,
last night we made two changes to our BIRD config:
* enabled ASPA validation (logging only)
* added "-R" to BIRD_ARGS (/etc/bird/envvars)
after that we run "configure" on birdcl.
After that bird started to crash in a loop.
We decided to rollback the ASPA configuration change to restore a
working setup. This did not help.
Then we decided to remove "-R" from BIRD_ARGS and that helped.
For this reason we did not include the ASPA config changes in this email
since they appear to be not relevant for the crashes.
We assume "-R" causes the crashes.
Is this a known bug that is solved in 3.2.0?
We would like to have graceful restart support but we are a bit hesitant
with "-R" now ;-)
