SAP Note 1456887 - Many processes select TRFCQIN with SAPLIRFC

Component : Queued RFC (qRFC) and transactional RFC (tRFC) -

Solution : https://service.sap.com/sap/support/notes/1456887 (SAP Service marketplace login required)

Summary :
The SAP Note addresses issues where work processes repetitively run with SAPLIRFC and perform sequential reads on TRFCQIN. This primarily occurs due to excessive logical units of work (LUWs) intertwined through dependencies, delaying the execution of qRFC scheduler's function CHECK_READY_QUEUES. A solution involves reducing inter-queue dependencies and applying enqueue enhancements via support packages. Developers should review and minimize such dependencies. Additionally, manual steps comprise creating a data structure ARFC_I_CK and an exclusive lock object E_Q_I_CK_R through SE80. This is pertinent for server stability and efficient resource management across various SAP_BASIS releases.
