Opened: Apr 04, 2019

Severity: 2-Critical


BIG-IQ sends a lot of request to the BIG-IP system to collect the stats it makes the BIG-IP slow and eventually GUI goes unresponsive.


ICRD requests wait longer in the ICRD queue, which can make the BIG-IP system becomes unresponsive. Policy Creation, Device Overview, and stats pages take more time to respond, and eventually, the GUI becomes unresponsive on these three pages. Lot of process terminated/re-created messages in restjavad logs.


-- BIG-IQ monitoring a large BIG-IP configuration. -- With a very large number of requests, and with resource-expensive requests.


Remove the BIG-IP device from the BIG-IQ and restart the mcpd.

Fix Information

The system now handles the queue so that there is time for BIG-IP system to recover and become responsive.
