Yukarıdaki gibi bir hata alıyorsanız tomcat arkaplanda açık kalmıştır. Linux/Unix tabanlı sistemlerde şu şekilde bu sorunu çözebilirsiniz.

ps -x | grep tomcat

yazarak tomcat’in process numarasını bulursunuz.

Örnek:

14293 ?? 4:13.88 /Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home/bin/java -Djava.util.logging.config.file=/Users/furkanzumrut/apache-tomcat-7.0.53/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Xms128m -Xmx1024m -Djava.endorsed.dirs=/Users/furkanzumrut/apache-tomcat-7.0.53/endorsed -classpath /Users/furkanzumrut/apache-tomcat-7.0.53/bin/bootstrap.jar:/Users/furkanzumrut/apache-tomcat-7.0.53/bin/tomcat-juli.jar -Dcatalina.base=/Users/furkanzumrut/apache-tomcat-7.0.53 -Dcatalina.home=/Users/furkanzumrut/apache-tomcat-7.0.53 -Djava.io.tmpdir=/Users/furkanzumrut/apache-tomcat-7.0.53/temp org.apache.catalina.startup.Bootstrap start

Bizim process numaramız 14293’müş.

kill -9 14293 yazarak bu arkaplanda çalışan process’i sonlandırabiliriz.
