Anyway here is my patch: --- httpd.rpmsave 2004-05-28 16:43:58.000000000 +0200 +++ httpd 2004-06-29 18:20:47.000000000 +0200 @@ -66,6 +66,15 @@ echo -n $"Stopping $prog: " killproc $httpd RETVAL=$? + removeipcs=`ipcs -s -c | grep apache | cut -d ' ' -f 1` + numipcs=`echo $removeipcs | wc -w` + if [ $numipcs != 0 ] + then + echo + echo -n $"and removing $numipcs ipcs: " + echo $removeipcs | xargs -n 1 ipcrm -s + sleep 2 + fi echo [ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile} } Note: I've just done this on a machine which has Apache 2 and Apache 1.3 running concurrently. In this situation it gets a bit more tricky because the ipcrm command inadvertently kills the Apache 1.3 process which has some ipcs open. So I have to restart it manually. I still haven't managed to debug exactly why this happens... David
