nope, not getting any OOM errors at all. Just a hung server every couple weeks. When it hangs JRUN thread metrics indicate all is well, no huge set of qued requests and 0 delayed requests and only 2 to 5 current threads being worked. Memeory according to JRUn is fine. Memeory according to task manager is high and CPU use is maxed. Its like a slow process of death, lol. I'm convinced its this one guys app that continually does big queries and continually gets pages running 15 to 25 secs long. Once I segregate this app and make use of your suggestions we shall see.
I'm supposed to be developing not spending hours in this abyss. We are actually thinking of scheduling a service restart like once a week to clear out whatever is happening. A horrible approach, but cheaper in our situation.
