2050354 - Troubleshooting network problems between the HANA Instance and SAP application servers


Network problems may result in a variety of symptoms/problems, including but not limited to:

  • A significant increase in database response time on SAP side (transaction ST03n) is reported. Workprocesses are stuck in "sequential read" according to transactions SM50/SM66 even though no database activity is visible on HANA side and no excessive statement runtimes can be identified.

  • Transactions might abort with a variety of SQL errors. The following ones are most common in this situation:
    • 10807 - Connection Loss
    • 10108 - Session Reconnect
  • In some cases these errors are accompanied by secondary error codes that put an even stronger emphasis to a problem on network layer:
    • System call 'recv' failed, rc=110:Connection timed out
    • System call 'recv' failed, rc=10060:A connection attempt failed because the connected party did not properly respond

The exact error codes are depending on the operating system that is used on client (SAP) side.
