Hi @AEM_user25
Are you doing any heavy activities on author environment? Is there any background activity are happening in your application? i mean scheduler, event handler etc.?
check your /bin/start.bat file Check for these line:
if not defined CQ_JVM_OPTS set CQ_JVM_OPTS=-Xmx1024m -XX:MaxPermSize=256M -Djava.awt.headless=true -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n
Try to increase the Xmx, MaxPermSize to
CQ_JVM_OPTS=-Xmx2048m -XX:MaxPermSize=512M
Check your error.log, applicqtion specific logs.
