We see periodic instances where our MII instance begins to quckly degrade in performance and within the hour causes a "503 Service Unavailable" error. When this begins to occur we can see one (or several) http worker threads that have been running for a while (10-15 min). This seems to propagate to the other threads and eventually they all hang, which is when the error occurs.
In looking at the log, there are no errors showing for the user that has the hung thread.
Also, there are no deadlocks occuring in on our SQL database.
Lately, this is occuring once a week.
Does anyone know what is causing this and if we may be missing a parameter setting in our NW instance?
MII 12.1.9 (Build 116)
NW CE 7.11 SP10.
Thanks,
