Hello Rob,

<BUG> Assertion 'DG_IS_LOCKED(p->domain)' failed at lib/resource.c:449

Anyone seen this before/know what this is about?

this is an internal error where somebody (probably me) wrote the code so badly that it tries to request a resource without having a proper lock acquired. This assertion is a last-resort guard against locking errors, and it's fatal because it guards against some very nasty scenarios, all including memory stomped all over with no real possiblity to debug anything. We'd love to not see that error, and therefore if you were so kind to recover the corefile and send it to us, we will examine that and fix that bug. I have no idea what exactly may have happened. This is a generic memory allocation function which is called from hundreds of places, so generally we need to see at least the whole stacktrace to know in which case the locking constraint has been violated. Thank you and sorry for the crash. Have a nice day! Maria -- Maria Matejka (she/her) | BIRD Team Leader | CZ.NIC, z.s.p.o.
