Summary :
SAP Note addresses long-running programs that terminate prematurely during background processing. The issue manifests in the gateway trace file with specific error entries regarding conversation IDs. The error arises when an RFC connection, secured using SNC, doesn't correctly initialize the SNC channel due to a kernel flaw. Workarounds include disabling SNC or modifying the rdisp/snc_max_hold_time parameter, though these can impact system performance. A kernel patch provides a permanent fix, allowing settings modification via the TH_CHANGE_PARAMETER function to manage this issue effectively.
