1914112 - HTTP session times out before the time limit defined in rdisp/plugin_auto_logout or rdisp/gui_auto_logout


  • The connection to the SAP system is lost after 30 minutes of inactivity. As consequence the users have to logon several times during the day, which is unnecessary. Note that parameter rdisp/plugin_auto_logout (or rdisp/gui_auto_logout) is set to a value higher than 1800 (30 minutes).
  • Users are getting disconnected during a small time than the defined rdisp/plugin_auto_logout or rdisp/gui_auto_logout;
  • Users complain about lost connections while the following entries are logged to the System Log (transaction SM21):
    HTTP/RFC session was deleted following timeout
  • At the work process trace (which can be found in SM21);
    M ***LOG R2G=> ThPlgTimeout, Timeout (Txxx_Uxxxx, security session timed o) [thxxmode.c 4137]
    M ThPlgTimeout: timeout reason: security session timed out
    M ThPerformDeleteThisSession: switch off statistics
