Error: Maximum number of open sessions reached

You may encounter the error "Maximum number of open sessions reached" when trying to log in to the server. The frequency of this error increases if you are using multiple machines and VPN connections. Especially after a computer goes to sleep or restarts, you are not able to manually select your old IP when reconnecting to VPN, which results to new sessions being created with each reconnect.

Workaround: We are working on a more permanent solution to terminate expired sessions. Currently, you can utilize any of the following workarounds:

  • Log out from current sessions before switching your IP or connection. We also recommend closing the browser as an open browser open can send a ping to the server, which will keep the session alive indefinitely.

  • Reduce the tomcat session timeout to 5 minutes:

    • Navigate to <server>/3rdparty/tomcat/conf/web.xml

    • Update the default session timeout to:

      <session-timeout>5</session-timeout>
  • Restart the server.
