Summary :
Processes in SM50 may display SAPLQOWK or SAPLQIWK alternating with SAPLSYBD extensively, paired with SMQR or SMQS showing a WAITING status. Additionally, workprocesses might hang while accessing QSENDDEST or QIWKTAB. The issue generally stems from a lack of resources, specifically insufficient workprocesses dedicated to qRFC/tRFC. Utilization of SMQR and SMQS is advised to monitor resources status. Application of the support package or corrections provided can mitigate excessive database updates on QSENDDEST or QIWKTAB which could exceed 100 updates per second when resource issues are not addressed.
