You might want to strace (truss, ktrace, whatever) the processes in
question to make sure that NFS is the problem (though I would not be
surprised if it is).
Also, take a look at these:
http://www.cfengine.org/docs/cfengine-Reference.html#index-MaxCfengines-60
http://www.cfengine.org/docs/cfengine-Reference.html#IfElapsed
Just to be extra safe, I also use a cron job:
#!/bin/sh
PATH=/bin:/usr/bin:/sbin:/usr/sbin; export PATH
SELF=`basename $0`
UNAME_N=`uname -n`
if test `uname` = SunOS; then
PS=`/bin/ps -eo uid,pid,args`
else
PS=`/bin/ps ax`
fi
NUM_CFAGENTS=`echo "$PS" | grep [c]fagent | wc -l | awk '{ print $1 }'`
if test "$NUM_CFAGENTS" -gt 4; then
echo $SELF: More than 4 cfagents are running on $UNAME_N.
echo $SELF: Assuming something went wrong.
echo $SELF: Killing all cfengine processes.
which pkill >/dev/null 2>&1
if test "$?" != 0; then
echo $SELF: Unable to locate \"pkill\" in $PATH.
echo $SELF: You probably want to kill all cfagents by hand.
echo $SELF: Aborting.
fi
pkill -u root cfagent
pkill -u root cfexecd
sleep 3
pkill -9 -u root cfagent
pkill -9 -u root cfexecd
fi
Best,
