Do you know the Parent Process ID? If so you can kill that and the
pattern. Also try this if no dice:

# pkill -9 -f syncCalendarFromGA.php ; \
pkill -9 -f syncCalendarFromGA.php ; \
pkill -9 -f syncCalendarFromGA.php ; \
pkill -9 -f syncCalendarFromGA.php ; \
pkill -9 -f syncCalendarFromGA.php ; \
pkill -9 -f syncCalendarFromGA.php

If that doesn't do it... then add "-P $PPID" before the "-f" where you
know the Parent ID in place of $PPID.

You also have to use "-f" with pkill to get it to match anything other
than "php" 

From the man page:

	-f, --full
		The pattern is normally only matched against the process
		name.  When -f is set, the full command line is used.

That is why I included it.
