error: restarting script because .git/FETCH_HEAD changed

I restart node.js server with forever by watchin files. Every few minutes I get message: error: restarting script because .git/FETCH_HEAD changed which restarts my server.

How to avoid that? It shall restart upon file change not git head change.

Watching script:

HOME=/root forever \
    --pidFile $PIDFILE \
    -a \
    -l $LOGFILE \
    --minUptime $MIN_UPTIME \
    --spinSleepTime $SPIN_SLEEP_TIME \
    --watch \
    --watchDirectory=$APPLICATION_PATH \
    start $APPLICATION_PATH$APPLICATION_SCRIPT 2>&1 > /dev/null &
RETVAL=$?
log_end_msg $RETVAL
