Comment # 8 on bug 960118 from Bin Liu

Another condition is that I used the following scripts to run corosync binary
got more that 60 times, there is no error, while use systemctl could occur the
issue:

#! /usr/bin/bash

while [ 1 -eq 1 ]
do
    corosync -f &
    rtn=$?
    echo "corosync -f& returned $rtn"
    if [ $rtn -ne 0 ]; then
        exit $rtn
    fi
    sleep 5
    corosync-cfgtool -s
    sleep 5
    killall -SIGTERM corosync
    #rm -rf /var/run/corosync.pid
    #killall -9 corosync
    rtn=$?
    echo "killall -SIGTERM corosync returned $rtn"
    if [ $rtn -ne 0 ]; then
        exit $rtn
    fi
    sleep 10
done

and from the log I found the following record:
