#57 Crash on graceful Apache reload

[Dustin C. Hatch]

After upgrading to Apache 2.2.23 recently, I found that initiating a graceful reload of a running Apache process (i.e. /etc/init.d/apache2 reload) would cause Apache to crash. By turning on debug logging, I was able to find this message, indicating that the problem was caused by mod_auth_kerb:

apache2: threads.c:351: krb5int_key_register: Assertion `destructors_set[keynum] == 0' failed.
[Thu Dec 27 20:04:58 2012] [notice] seg fault or similar nasty error detected in the parent process

Please let me know if there is a way I can provide additional information in order to help you track down this problem.
