I'm not sure if it's copy&paste typo, but the size test is not allowed in the
"check process" context:
--8<--
check process tomcat7 with pidfile /var/run/tomcat7.pid
if size = 0 then exec "/bin/rm /var/run/tomcat7.pid"
<------------------------ error
start program = "/etc/init.d/tomcat7 start" with timeout 60 seconds
...
--8<--
The "check file" test is not necessary ... the pidfile based process check will
automatically trigger restart if the pidfile is missing.

Martin
