  • Did you look in that System Event Log, or directly to Tomcat's `logs/console.out` file? Any error there? Btw. I had run pretty big Liferay instances in my previous job, but never needed PerSize bigger than 512m. Are you sure you need to increase `XX:MaxPermSize` and not `Xmx` (the heap memory)? – Jozef Chocholacek Aug 07 '17 at 10:04

    What does the Tomcat log file say? What other memory settings do you have? For better diagnosis you should try to start the tomcat manually as a first try. If theres a OutOfMemoryError you should activate [heap dump creation](https://stackoverflow.com/questions/542979/using-heapdumponoutofmemoryerror-parameter-for-heap-dump-for-jboss) and look into the heap dump to see what uses the memory. – Markus Aug 07 '17 at 10:24
  • in that case i have to increase memory size. i have 16GB of RAM. i would like to increase it to 4GB – Stefan Hofer Aug 07 '17 at 13:24
  • I looked in the system eventlog. Found no errors, i looked up different pages for mor information but nothing helped till now. i attached the log files. – Stefan Hofer Aug 07 '17 at 13:25
