The appliation of our company has memory leak problem, and we have to restart it once a week.

already added the -XX:+HeapDumpOnCtrlBreak option, but didn't work.
set JAVA_OPTIONS=%JAVA_OPTIONS% -XX:+HeapDumpOnOutOfMemoryError -XX:+HeapDumpOnCtrlBreak -XX:HeapDumpPath=E:\bea\user_projects\domains\app_domain_bck
