Hi Steven, I was finally able to run a test on the failing rspamd, I am not familiar with reading this core dumps and followed the instructions given in the URL, i got following from lldb:
lldb `which /opt/local/bin/rspamd` -c /cores/core.89034 (lldb) target create "/opt/local/bin/rspamd" --core "/cores/core.89034" Core file '/cores/core.89034' (x86_64) was loaded. (lldb) bt all * thread #1, stop reason = signal SIGSTOP * frame #0: 0x000000000f4c74b1 librspamd-server.dylib`ue2::hs_compile_multi_int(char const* const*, unsigned int const*, unsigned int const*, hs_expr_ext const* const*, unsigned int, unsigned int, hs_platform_info const*, hs_database**, hs_compile_error**, ue2::Grey const&) + 513 frame #1: 0x000000000f4c7c40 librspamd-server.dylib`hs_compile_multi + 96 frame #2: 0x000000000f2daff5 librspamd-server.dylib`rspamd_multipattern_compile + 370 frame #3: 0x000000000f376b70 librspamd-server.dylib`rspamd_language_detector_init + 5664 frame #4: 0x000000000f31d570 librspamd-server.dylib`rspamd_config_read + 1262 frame #5: 0x000000010d479de8 rspamd`load_rspamd_config + 107 frame #6: 0x000000010d479499 rspamd`main + 1373 frame #7: 0x00007fff55d0f015 libdyld.dylib`start + 1 (lldb) It created two core dumps every minute until I unloaded rspamd.
