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": https://www.geeksforgeeks.org/segmentation-fault-sigsegv-vs-bus-error-sigbus/ 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? David
