It appears it is a memory leak caused by "high number" of SID lookups. The DCs dont release the memory, the DCs become unresponsive. I cant hand out customer data, but I'm interested in knowing if Dynatrace is aware of such an issue, and if so, can i get an update? If not, would Dynatrace like to know more?
