Hi, I have detected segfaults in pop3 and imapd services in my dbmail 3.1.17 (Debian 7) server. Logs in /var/log/kern.log: Oct 27 10:40:03 dbmail01 kernel: [21722970.963966] dbmail-pop3d[25341] general protection ip:7fb8ad72b80a sp:7fff5bf5f768 error:0 in libdbmail.so.0.0.0[7fb8ad6e7000+6b000] Oct 27 11:16:30 dbmail01 kernel: [21725158.293150] dbmail-pop3d[25262]: segfault at 1fb9 ip 00007f4f7e98e80a sp 00007fffbd2d7c78 error 4 in libdbmail.so.0.0.0[7f4f7e94a000+6b000] Oct 27 14:11:02 dbmail01 kernel: [21735629.206895] dbmail-pop3d[29032] general protection ip:7fe0b4c8080a sp:7fffdf976aa8 error:0 in libdbmail.so.0.0.0[7fe0b4c3c000+6b000] Oct 27 14:17:50 dbmail01 kernel: [21736037.204306] pool[29043]: segfault at 0 ip 00007f1c8471ce20 sp 00007f1c7e368c80 error 4 in libzdb.so.9.0.2[7f1c84714000+1a000] Oct 28 16:18:17 dbmail01 kernel: [21829660.233119] pool[23525]: segfault at 0 ip 00007f1f0eb4de20 sp 00007f1f05f9f690 error 4 in libzdb.so.9.0.2[7f1f0eb45000+1a000] Other posts mention that DoS attacks may be a reason for these crashes, but I am already running APF/BFD/iptables to protect the server in realtime. Dbmail restart is needed in this case. Any clues? Sincerely.
