It appears signal 10 is a bus error:

https://github.com/freebsd/freebsd/blob/master/sys/sys/signal.h


This page clarifies the meaning of "bus error":

My guess would be the latter case -- unaligned memory access.  This 
could be a coding bug (struct not laid out for 64-bit architecture?) or 
a misconfigured compile (?).


Where did your rspamd binary come from -- package?  port?  downloaded 
and built by hand?
