Perhaps you killed (using -9) some processes so this one remained hanging? Otherwise, this is not possible, i.e. only one operation on a resource is run. > root 2271 1 0 10:26 ? 00:00:00 /bin/sh > /usr/lib/ocf/resource.d//intact/tomcat start > tomcat 2307 1 21 10:26 ? 00:00:02 /usr/lib/jvm/java/bin/java > -Djava.util.logging.config.file=/home/tomcat/tc-1/conf/logging.properties > -Dname=tomcat -Djava.awt.headless=true -Djava.library.path=/usr/lib64 > -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Xmx1024M > -Djava.endorsed.dirs=/opt/tomcat/endorsed -classpath > /opt/tomcat/bin/bootstrap.jar -Dcatalina.base=/home/tomcat/tc-1 > -Dcatalina.home=/opt/tomcat -Djava.io.tmpdir=/home/tomcat/tc-1/temp > org.apache.catalina.startup.Bootstrap start > > Note the two 'tomcat start' processes above. > Each restart produces successively more copies of the 'tocmat start' process.

The '&' at the end of the line certainly makes to run in background. Otherwise, the start action goes into infinite loop waiting for the monitor of the resource to succeed. If it never does, then lrmd will timeout and kill the process.
