Dear Sam, at first thank you for glorious work with spamdyke! I'm using it since several years and it's very helpful to me.
At 30th march 2015 I've done an upgrade to version 5 (previous: last 4 version). Since then I often get a segfault in spamdyke: Tue Apr 7 12:05:19 2015] spamdyke[13607]: segfault at 14 ip 00007f60ce1e3ba8 sp 00007fff6bac3ce0 error 4 in libc-2.14.1.so[7f60ce19b000+187000] [Tue Apr 7 12:16:20 2015] spamdyke[13959]: segfault at 14 ip 00007fe1145bdba8 sp 00007fffa6426b90 error 4 in libc-2.14.1.so[7fe114575000+187000] [Tue Apr 7 12:47:31 2015] spamdyke[15309]: segfault at 14 ip 00007f9971e49ba8 sp 00007fffa03aad20 error 4 in libc-2.14.1.so[7f9971e01000+187000] [Tue Apr 7 15:30:51 2015] spamdyke[21795]: segfault at 14 ip 00007fb0cac66ba8 sp 00007fff209aa400 error 4 in libc-2.14.1.so[7fb0cac1e000+187000] [Tue Apr 7 16:13:02 2015] spamdyke[23130]: segfault at 14 ip 00007f47bd14eba8 sp 00007fff5b5fd1e0 error 4 in libc-2.14.1.so[7f47bd106000+187000] [Tue Apr 7 17:22:50 2015] spamdyke[26691]: segfault at 14 ip 00007f24e499bba8 sp 00007fff0cbd2060 error 4 in libc-2.14.1.so[7f24e4953000+187000] [Tue Apr 7 22:37:46 2015] spamdyke[6768]: segfault at 14 ip 00007fcd7c1ffba8 sp 00007fff0fd874f0 error 4 in libc-2.14.1.so[7fcd7c1b7000+187000] [Tue Apr 7 22:37:48 2015] spamdyke[6775]: segfault at 1a ip 00007fb2f498eba8 sp 00007fff6f12c380 error 4 in libc-2.14.1.so[7fb2f4946000+187000] [Tue Apr 7 22:37:49 2015] spamdyke[6780]: segfault at 1a ip 00007f4e9ee6fba8 sp 00007fff517bbbd0 error 4 in libc-2.14.1.so[7f4e9ee27000+187000] [Tue Apr 7 22:38:11 2015] spamdyke[6764]: segfault at c ip 00007ffc08375ba8 sp 00007fff0c363ba0 error 4 in libc-2.14.1.so[7ffc0832d000+187000] [Tue Apr 7 23:15:12 2015] spamdyke[10219]: segfault at 14 ip 00007ff1e6e54ba8 sp 00007fffad8b0870 error 4 in libc-2.14.1.so[7ff1e6e0c000+187000] [Tue Apr 7 23:30:42 2015] spamdyke[10658]: segfault at 14 ip 00007f7e5db7eba8 sp 00007fff00aa9eb0 error 4 in libc-2.14.1.so[7f7e5db36000+187000] [Wed Apr 8 00:04:28 2015] spamdyke[12967]: segfault at 14 ip 00007f53171f2ba8 sp 00007fff6b2988d0 error 4 in libc-2.14.1.so[7f53171aa000+187000] [Wed Apr 8 00:04:51 2015] spamdyke[12983]: segfault at 14 ip 00007f08fecd3ba8 sp 00007fff780fdd80 error 4 in libc-2.14.1.so[7f08fec8b000+187000] [Wed Apr 8 00:18:19 2015] spamdyke[13457]: segfault at 14 ip 00007fb3059d7ba8 sp 00007fffb221b350 error 4 in libc-2.14.1.so[7fb30598f000+187000] [Wed Apr 8 00:18:31 2015] spamdyke[13463]: segfault at 14 ip 00007f1a1a635ba8 sp 00007fff32b32180 error 4 in libc-2.14.1.so[7f1a1a5ed000+187000] It's an OpenSuse 12.1 under Plesk with Qmail.
