We have been experiencing some weird thing going lately, all the adapters (local to the broker and remote as well) slow down (or pause, take long time to process documents, similar wording). And this slow down occurs on an hourly basis. These adapters use different brokers and these brokers belong to different broker servers (v5 btw). When this slow down happens, CPU is about 50% utilized, mem is about 50% constant, no swapping, not much IO. The only common resource that these local/remote adapters use is the brokers. No hourly batch, no hourly schedule task. This slow down always happens around the top of the hour, during heavy load, during light load. No error from all tracing/monitoring. I have run out of things which I could explain this hourly slow down, so does the vendor, wM. Did anyone experience something like this before? I have worked with this thing for 4 years now and I have not seen this hourly slow down “phenomenon”.
