Bug#493573: apache2: Restart and reload does not work

[Vladislav Kurz <vladki@uran.webstep.net>]

Package: apache2.2-common
Version: 2.2.9-6
Severity: important


After upgrade to lenny apache started to fail after logrotate.
I found that after reload or restart it was still running, listening on
network socket but not answering reqests. The only way was to kill it
with kill -9. Log for reload says just:

[notice] Graceful restart requested, doing restart

Log for restart says this:

[error] child process 27290 still did not exit, sending a SIGKILL
[error] child process 27291 still did not exit, sending a SIGKILL
[error] child process 27292 still did not exit, sending a SIGKILL
[error] child process 27293 still did not exit, sending a SIGKILL
[error] child process 27294 still did not exit, sending a SIGKILL
(the above lines were repeated 4 times)
[notice] caught SIGTERM, shutting down

After writing the notice about restart or shutdown, the old apache
process was still running, but not processing requests. New apache
process could not be started because ports were occupied:

(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
 failed!

I couldnt find any more info in logs. If you point me how to get more
debug info I'l provide it.

Regards
Vladislav Kurz
