After few hours of working with new selenium 2.20 i get this error:
WARNING: Client requested session 1331671421031 that was terminated due to FORWARDING_TO_NODE_FAILED 14.3.2012 5:46:55 org.openqa.grid.internal.ActiveTestSessions getExistingSession
what can be wrong. I never get this message with 2.19 version of selenium server.
There is also no other messages just this message all the time in console.
Per selenium wiki -
FORWARDING_TO_NODE_FAILED - The hub was unable to forward to the node. Out of memory errors/node stability issues or network problems
Are you sure you didn't have network related issue?
