My auth process is dumping core. This happens several times per day but dovecot can operate normally for hours between errors.
The crash occurs in src/auth/auth-policy.c, line 356:
t@1 (l@1) program terminated by signal SEGV (no mapping at the fault address) Current function is auth_policy_parse_response 356 context->request->policy_refusal = FALSE;
Further tracking shows this sets context->request to NULL:
"src/lib/iostream.c" line 54
array_foreach(&stream->destroy_callbacks, dc)
dc->callback(dc->context);Very occasionally I see:

Swapping keep-alive on/off changes crashing from very approximately once per day to some per hour. I guess there is some fundamental thread clash or keep alive time out clean-up failure.
