RedHat 4.2 on Alphaserver  1000A 5/333  ( single processor )
server runs standalone, although NFS is running, local disks 
are mounted by other machines, but the directory tree of this server is all
on local disks. 


>Description:
After a shell script run by a cron job stops apache and moves the log files,
then starts apache,  the server only runs for a few hours. Then the children die
 and the parent becomes unresponsive. 
HTTP Requests  hang untill timeout.
If I then kill the parent, then restart by hand, everything is fine.
This happened  consistently with  1.3.0 and 2 previous versions
( 1.2.4 and 1.2.5 )

No unusual messages appear in the error logs.
i.e. 
The end of the old log:::::::::::::::::::::::::::::

[Thu Sep  3 13:44:11 1998] [notice] Apache/1.3.0 (Unix) mod_perl/1.12 configured -- resuming normal operations
[Mon Sep  7 00:00:00 1998] [notice] httpd: caught SIGTERM, shutting down

The new log::::::::::::::::::::

[Mon Sep  7 00:01:16 1998] [notice] Apache/1.3.0 (Unix) mod_perl/1.12 configured
 -- resuming normal operations
[Mon Sep  7 10:28:23 1998] [notice] httpd: caught SIGTERM, shutting down
[Mon Sep  7 10:28:48 1998] [notice] Apache/1.3.0 (Unix) mod_perl/1.12 configured

I have looked high and low for any other desription of this bug, so I apologize 
if I missed mention of it. This is the shell script :

#!/bin/sh

dat=`date +%Y%m%d`

cd /home/logs
/usr/local/apache_1.3.0/sbin/apachectl stop
# kill `cat httpd.pid`
sleep 60 
# rm -f httpd.pid

set -- `ls`
mkdir $dat
for u
do
#       echo "$u -> $dat.$u"
        cp $u $dat/$dat.$u
        > $u
done

/usr/local/apache_1.3.0/sbin/apachectl start
 

Thanks for your attention.
