Package: bind9 Version: 1:9.5.0.dfsg.P2-1 Severity: important
syslog.log Sep 30 23:23:54 derek kernel: [791273.512364] named[2244]: segfault at dededef2 ip b7eaad0e sp b7549f90 error 7 in libdns.so.43.0.1[b7e40000+141000] I use bind9 running locally on my desktop box as the local recursive resolver. Although this box has some unusual history (ran sid) as far as I can ascertain it is running correct version of bind9 and libraries for lenny. The bind9 config is relatively straight forward, and close to the Debian default, with addition of some local authoritative zones. Twice recently bind9 has stopped, dumping two core files in /var/cache/bind. On both occasions problems were seen resolving some names (reporting timeouts) immediately before the crash. -rw------- 1 bind bind 58179584 2008-09-30 23:23 core.2243 -rw------- 1 bind bind 43302912 2008-09-22 19:58 core.2463 On one occasion I immediately ran "rndc dumpdb" when I encountered issues with name resolution, and the crash took place a few seconds after the database was written to /var/cache/bind/named_dump.db -rw-r--r-- 1 bind bind 81933 2008-09-30 23:20 named_dump.db Please advise if this information would be useful in diagnosing bind issues. If any libraries are the wrong version for lenny I will probably reinstall. I couldn't see other reports of this issue, although there are other reports of bind silently stopping, which could be related.
