Answer 1

Read JVM options explained. Here're excerpts from it:

• If you are frequently recieving java.lang.OutOfMemoryError: Java heap space errors you should increase -Xmx value.
• Normally -XX:PermSize and -XX:MaxPermSize do not need to be adjusted but if you are seeing java.lang.OutOfMemoryError: PermGen space events often you can increase these values.
• -XX:MaxJavaStackTraceDepth - This specifies how many entries a stack trace for a thrown error or exception can have before a StackOverflowError is thrown. So if you are dealing with huge stack traces you can use this option to increase the allowed entriers before overflow.
