Opened: Jul 13, 2020 Severity: 3-Major
With some configurations, executing a command such as 'tmsh show security firewall global-rules active' loops continuously, causing stat counters to rise, and possibly log messages to be written to /var/log/ltm.
The iRule loops continuously, causing stat counters to rise, and possibly logging messages in /var/log/ltm.
-- AFM is routing traffic to a Virtual Server through the 'Send to Virtual' option. -- The target Virtual Server uses the 'LB_FAILED' iRule to select a new Virtual Server through virtual command and 'LB::reselect'.
This configuration should be avoided, but if it is used, and if this does happen, you can restart tmm: bigstart restart tmm This stops the current looping, until it is triggered again. Impact of workaround: Traffic disrupted while tmm restarts.
