I've been having this problem recently with our server and I've never seen anything like it before. I'm hoping someone in the community might be able to give me some guidance...
We run a ColdFusion 10 Standard server (recently patched with update 12), which handles about 30 requests per second on average.
Lately, we've been experiencing some very odd performance issues, so I've been leaving FusionReactor open on my screen pretty much all day long. And what I've noticed is really bizarre.
Periodically, the metrics graphs will show a drop-off in requests from the usual 20-40 to 0. This last for about 5 seconds, and when the requests come back, they shoot right up to the max (our server set its max at 100). It's almost as if something is blocking the requests from getting through for those few seconds, and then we get flooded all at once. Either that, or FusionReactor isn't properly recording the traffic. At one point this morning this was happening every minute or so, such that our server was just choking on the requests and we were forced to just reboot the whole machine.
Has anyone experienced this before? Or might be able to point me in a good direction?
