Package: apache2
Version: 2.2.6-1
Severity: normal
My machine was keeping tons of apache2 processes around (I suspect due
to the daily logrotate restart), see attached images.
$ ps fax | grep apache2
4204 ? Ss 0:00 /usr/sbin/apache2 -k start
4210 ? S 0:00 \_ /usr/sbin/apache2 -k start
$ sudo strace -p 4210
Process 4210 attached - interrupt to quit

Process 4210 detached
Stracing the father process 4204 reveals a loop of this:
waitpid(4210, 0xbfd03878, WNOHANG|WSTOPPED) = 0
getpgid(0x1072) = 4204
getpgrp() = 4204
kill(4210, SIG_0) = 0
rt_sigprocmask(SIG_BLOCK, [CHLD], [], 8) = 0
rt_sigaction(SIGCHLD, NULL, {SIG_DFL}, 8) = 0
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
nanosleep({1, 0}, {1, 0}) = 0
waitpid(4210, 0xbfd03878, WNOHANG|WSTOPPED) = 0
