tmm processes enter a restart loop when trying to run DNS Express (DNSX) on i11000 platforms with htsplit disabled.
tmm processes enter a restart loop. In this condition, DNSX does not run, though other DNS functions are unaffected.
-- i11000 platform. -- htsplit disabled (sys db scheduler.splitplanes.ltm set to false). -- Trying to run DNSX.
Enable htsplit using the following command: modify sys db scheduler.splitplanes.ltm value true
tmm no longer cores under these conditions. However, you cannot use DNSX with htsplit disabled; htsplit must be enabled. Note: DNSX works as expected with htsplit enabled, both before and after the fix.
