Question Why does the routing protocol process use excessive memory? Answer The routing protocol process uses hundreds of megabytes of RAM in the Routing Engine to store information needed for the operation of routing and related protocols, such as BGP, OSPF, IS-IS, RSVP, LDP and MPLS. ...
Question How do I determine whether there is a memory leak in the routing protocol process? Answer Memory leaks are typically the result of a seemingly unbounded growth in the memory usage of a process as reported by the show system processes extensive command. There are two...
Question What can I do when there is a memory shortage even after a swap? Answer It is not recommended for the system to operate in this state, notwithstanding the existence of swap. The protocols that run in the routing protocol process usually have a real-time requirement that cannot...
Question How do I monitor memory swap activity? Answer When the system is under memory pressure, the pageout process reuses memory from the free, cache, inact and, if necessary, active pages. You can monitor the swap activity by viewing the syslog message reported by the kernel during...
Question What does the RPD OS MEMHIGH message mean? Answer The RPD OS MEMHIGH message is written into the system message file if the routing protocol process is running out of memory. This message alerts you that the routing protocol process is using the indicated amount and percentage...
Question What is the task timer? Answer The source of a routing protocol process memory leak can usually be identified by dumping the timers for each task. You can use the show task command to display routing protocol tasks on the Routing Engine. Tasks can be baseline tasks performed...
Displaying rpd Statistics in Simple Horizontal Bar Graphs For SLAX version 1.0 and higher, you can use the op-rpd-mem script to display rpd statistics in simple horizontal bar graphs. This op script uses the command "show task memory detail". The library lib-graph.slax is content...
The op-rpd-mem script displays rpd statistics in simple horizontal bar graphs. This op script uses the command "show task memory detail". The library lib-graph.slax is content independent (resuable). Read the document op-rpd-mem #How-To #Slax #op-script #RPD
