When taking a qkview on a heavily loaded BIG-IP device (with lots of connections) running 12.1.0 or 12.1.1, the qkview utility may take a very long time to complete (30+ minutes) or cause tmm to restart. This is due to a new qkview command that was added to gather a list of recent connections with the tmsh show sys connection command, which has a significant performance impact when run while the BIG-IP is heavily loaded.
Qkview command can take an exceedingly long time to run (30+ minutes). Traffic disrupted while tmm restarts.
This can occur on the following versions: - 12.1.0 including 12.1.0 HF1 and 12.1.0 HF2 - 12.1.1 including 12.1.1 HF1 This can occur when the BIG-IP is heavily loaded and while running the qkview command.
Do not run the qkview command if the device is heavily loaded.
Removed offending "show sys connection" command from qkview utility.
