On an SRX running 15.1X49-D130 or lower, with BGP configured, BGP might not free the allocated memory of routing instance names which are called during executing operational command "show route" or "show bgp xxx", this causes a slow rpd memory leak.
The SRX may not be reachable.
There may be "severe memory pressure" messages.Examples:Jun 13 21:29:30.748 srx1500 /kernel: %KERN-3: rt_pfe_veto: Severe memory pressure, low-free-pages is below threshold. Op 4 err 55, rtsm_id 0:-1, msg type 72Jun 13 21:29:30.748 srx1500 /kernel: %KERN-3: rt_pfe_veto: free page threshold = (1933) number of pages free = (716) number of pages on buffer cache queue = (1216) curproc = jsrpd
To recover the box, it needs to be rebooted. PR1124923 addresses the permanent solution.
