>Description:
when stop or restart apache only children are killed but never the PID which is still on,

and ipcs is not cleared semaphore from Uid Apache still on
>How-To-Repeat:
very easy:
with this flags from "compiled with", turn on the TransferLog with rotatelogs or cronolog,
like
TransferLog "|/path to cronolog --symlink=/path to file/ /path to file%d%m%Y/"
TransferLog "|/path to rotatelogs /path to file/ 28800"
>Fix:
i have no way to avoid to it

very urgent please..
