Opened: Apr 19, 2021 Severity: 3-Major
-- Restjavad may become unstable if the amount of memory required by the daemon exceeds the value allocated for its use. -- Restjavad might restart frequently due to the JVM heap running out of memory.
Memory leaks/out-of-memory errors might cause iControlRest API intermittently unavailable.
-- BIG-IP system with no extra memory given to restjavad. -- The configuration contains a large number of configuration items w.r.t to APM, LTM, security(ASM), and SSL Orchestrator. -- The memory required by the restjavad daemon may grow significantly in system configurations with either a high volume of device statistics collection (AVR provisioning) or a relatively large number of LTM objects managed by the REST framework.
-- Limit the active use of the DashBoard and restart java (bigstart restart restjavad) when the memory levels peak. OR -- Increase the memory allocated for the restjavad daemon (e.g., 2 GB), by running the following commands in a BIG-IP terminal. tmsh modify sys db restjavad.useextramb value true tmsh modify sys db provision.extramb value 2048 bigstart restart restjavad Note: This may lead to an impact on multi-module systems with ASM as approximately only 50-60% of provision.extramb value would be allocated as extra host memory and restjavad may take up to 80% of provision.extramb. It also lowers the ASM-specific host allocation resulting in some tighter memory constraints on ASM daemons. Try to use the smallest value that works.
