Summary :
SAP Note addresses the syslog Q0I error, resulting from failed network connection writes. The error specifically occurs when work processes attempt to communicate with the Internet Communication Manager (ICM) post-restart, without knowing ICM's disconnection. The trace files reveal broken connections and send failures. This malfunction prompts necessary kernel patches to check connection statuses before writing operations, ensuring such communication errors are rectified. SAP advises updating to the specified patch level under 'SP Patch Level' for resolution, noting that dual corrections in the kernel comprehensively address the issue.
