Restjavad restarts frequently -- approximately every 5 minutes -- due to the JVM heap running out of memory


REST API intermittently unavailable.


-- BIG-IP system with no extra memory given to restjavad. -- The configuration contains a large number of configuration items related to APM access-policies, APM policy-items, APM policy agents, LTM nodes, LTM rules, DNS Requests, sys application services, LTM data-groups, LTM profiles, security bot-defense profiles, and sys file ssl-certs.


Give restjavad extra memory, using the following commands. The example below allocates 2 GB of extra memory to restjavad: tmsh modify sys db restjavad.useextramb value true tmsh modify sys db provision.extramb value 2000 bigstart restart restjavad To persist the change above with system reboots, save the configuration with: tmsh save sys config

Fix Information

Default restjavad heap memory has been increased to 384MB
