Just a hypothesis. During these off-peak hours some other applications are actively running (maintenance etc.), and as java is not intensively used, its memory is swapped to the hard disks.
Thus, when it awakens and does the GC, it takes so much time to wake up the memory walking through it to collect the garbage. What is memory consumption at night time? Are there memory-intensive tasks being performed at that time? May be restarting the tomcat can be scheduled after all those are done? (Or a forced GC, or filling memory with a bunch of dummy objects, up to Runtime.freeMemory()?) --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
