Summary :
SAP Note identifies performance issues concerning application servers running slowly, primarily reflected in lengthy user wait times and CPU load intensification. Traces in the dispatcher file showing "dp_high_prio_state to DP_HPRIO_TIMEOUT" suggest potential mishandling of High Priority Requests, introduced in kernel 3.0F. These requests require available work processes, which, if fully occupied, can halt further request processing and prevent new logins. To diagnose, administrators should utilize 'dpmon' with the respective Instance profile to examine dialog work process activities. It’s clarified that this is neither a dispatcher nor kernel error but could be linked to application-induced database blocks.
