Sometimes the APM RBA plugin resets and writes an error to the log that includes this phrase: [0x19fd874:459] Internal error (APM::RBA requested abort (trans end error)). The problem can happen intermittently and usually occurs when multiple tabs are used.


There are intermittent connection resets. Depending on the URL of the second tab, it should have terminated the existing session and started a new one, or it should have rendered a 404 page explaining that the access policy is already running in a different tab.


Most reproductions involve multiple tabs. End user starts access policy in one tab, and is delivered a login page. Then the end user opens a new tab, and attempts to evaluate the access policy in that tab. The reset comes from the RBA plugin, but this can be reproduced without Kerberos being configured.



Fix Information

Fixed intermittent resets when access policy execution in progress simultaneously from multiple browser tabs.
