Hello everyone, ASR9001 has some memory usage limits: - 1658M for a BGP process on a RSP - 1536M for a shared memory window on a LC Those limits seems to be unconfigurable.
Has anybody experienced any issues with these limits on high-loaded ASR9001 boxes? We have a surprisingly high memory usage while the typical router setup is pretty lightweight - 4-5 full feeds (couple of upstreams and RRs). The only probably uncommon thing is we use "Internet in a VRF" approach. #show processes memory detail location 0/RSP0/CPU0 > Tue May 19 19:39:12.592 Ural > JID Text Data Stack Dynamic Dyn-Limit Shm-Tot > Phy-Tot Process > ------ ---------- ---------- ---------- ---------- ---------- ---------- > ---------- ------- > 1054 1M 5M 516K 1485M 1658M 76M > 1491M bgp > #show memory summary location 0/0/CPU0 > node: node0_0_CPU0 > ------------------------------------------------------------------ > Physical Memory: 8192M total > Application Memory : 7988M (3811M available) > Image: 75M (bootram: 75M) > Reserved: 128M, IOMem: 0, flashfsys: 0 > Total shared window: 1327M > We have already had FIB inconsistency issues due to SHMWIN exhaustion despite the fact the total prefix amount was far from the platform limit (4M): > fib_mgr[184]: %OS-SHMWIN-3-ALLOC_ARENA_FAILED : SHMWIN: Failed to allocate > new arena from the server : 'SHMWIN_SVR' detected the 'fatal' condition 'VM > is exhausted or totally fragmented' > fib_mgr[184]: %ROUTING-FIB-3-ASSERT_RL : FIB internal inconsistency > detected > fib_mgr[184]: %ROUTING-FIB-3-PD_FAIL : FIB platform error: fib_leaf_insert > 5204 Cannot insert leaf > What are practical limits for BGP scaling on ASR9001 boxes? Could anyone share a memory usage stats? -- Best regards, Vladimir Troitsky _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
