Bug#550840: apache2-mpm-prefork: reload does not work: childs hangs on FUTEX_WAIT_PRIVATE
Package: apache2-mpm-prefork
Version: 2.2.9-10+lenny4
Severity: normal
After a reload by /etc/logrotate.d/apache2 the apache childs seems to
be hangling in
graceful ("G") state for days at least. Strace shows:
$ sudo strace -p 30838
Process 30838 attached - interrupt to quit
futex(0x7f9f7e3b2240, FUTEX_WAIT_PRIVATE, 2, NULL^C <unfinished ...>
Process 30838 detached
Some related info goes below. If you point me how to get more debug
info I'll provide it.
Apache is listening on two ip's:
$ cat /etc/apache2/ports.conf
Listen <ip1>:80
Listen <ip2>:80
$ php5 -m
