After configuring 3000 keycerts, the BIG-IP GUI is malfunctioning. It shows "unable to contact BIGIP device" and may become inaccessible until a reboot is performed
Due to this issue, GC overhead and TMUI are preventing the creation of virtual servers, pools, and other functionalities. Additionally, there are times when we cannot contact the BIG-IP device, which is causing disruptions for customers in their usual operations on BIG-IP
Once, after loading 3000 keys into the BIG-IP instance using the tmsh command, it caused OutOfMemory issues
To resolve the GC OOM issue, execute the following commands: tmsh modify sys db provision.tomcat.extramb value 512 tmsh save sys config bigstart restart tomcat
