We've been seeing a pretty severe problem with CF 11 Updater 7 (and now 8) where the active requests just spike out to our max and the server starts throwing timeouts and 503 errors.
We run a ColdFusion 11 Enterprise server (currently patched with update 6), which handles about 30 requests per second on average.
Periodically, the metrics graphs will just show a spike in active requests that jumps up to our max (100 threads). This last for about 15-20 seconds and then recovers, but accompanying it are usually 10-20 timeout errors and who knows how many 503's. And this ends up happening every 15 minutes or so. It's like something is slowing down the processing of pages, or holding them up for long enough to queue out of control.
We tried installing update 7 and it happened all day, so we rolled back out of it. When update 8 was released, we installed that and encountered the same problem. I'm guessing that it was actually in update 7 and the fact that updates are cumulative means I got it again.
Has anyone experienced this before? Is there any way I can install update 8 without 7?
