Hi, under heavy load our cluster is experiencing frequent OSD crashes. Is this a known bug or should I report it? Any workarounds? It looks to be highly correlated with memory tuning. it happens with both nautilus 14.2.16 and octopus 15.2.9. I have forced the bitmap bluefs and bluestore allocator. the cluster is ~60 nodes with 256GB ram and 25Gb NICs, ~1600 OSDs on 100g network. Typically it is happening when the traffic is above 100GB/s. Best regards, Andrej -14> 2021-03-09T14:10:30.105+0100 7fc128e05700 10 monclient: tick -13> 2021-03-09T14:10:30.105+0100 7fc128e05700 10 monclient: _check_auth_rotating have uptodate secrets (they expire after 2021-03-09T14:10:00.107344+0100) -12> 2021-03-09T14:10:30.210+0100 7fc119412700 5 osd.209 9539 heartbeat osd_stat(store_statfs(0xe68762a0000/0x40000000/0xe8d7fc00000, data 0x24b195d923/0x24c97c0000, compress 0x0/0x0/0x0, omap 0xf5dca, meta 0x3ff0a236), peers [6,8,11,21,22,23,24,25,26,27,28,29,34,35,37,38,65,86,87,90,120,128,129,135,136,140,150,153,154,160,184,188,192,193,203,208,210,217,229,233,242,248,254,25 6,275,277,282,290,311,313,324,326,331,339,348,369,409,411,413,466,477,532,535,538,539,542,544,546,548,552,554,556,558,561,576,580,600,601,604,612,614,624,625,631,657,689,695,704,717,738,739,740,766,790,810,812,833,839,890,891,895,903,909,916,926,927,946,960,965,991,1050,1055,1062,1064,1067,1069,1072,1073,1075,1077,1078,1079,1095,1100,1117,1125,1127,1141,1148,1149,1153,1155,1195,12 01,1202,1215,1229,1238,1253,1260,1283,1290,1298,1303,1329,1330,1349,1350,1388,1389,1422,1423,1430,1431,1434,1448,1455,1478,1479,1485,1488,1494,1497,1506,1516,1561,1564,1573,1574,1580] op hist [0,0,0,1,3,4,15,24,43,64,102,117]) -11> 2021-03-09T14:10:30.468+0100 7fc137cc0700 10 monclient: handle_auth_request added challenge on 0x55c08becf800 -10> 2021-03-09T14:10:30.543+0100 7fc1374bf700 10 monclient: handle_auth_request added challenge on 0x55c08becf400 -9> 2021-03-09T14:10:30.712+0100 7fc1384c1700 10 monclient: handle_auth_request added challenge on 0x55c08becec00 -8> 2021-03-09T14:10:31.029+0100 7fc137cc0700 10 monclient: handle_auth_request added challenge on 0x55c08becfc00 -7> 2021-03-09T14:10:31.033+0100 7fc12ca33700 5 prioritycache tune_memory target: 7264711979 mapped: 1564606464 unmapped: 47874048 heap: 1612480512 old mem: 5369698813 new mem: 5369698813 -6> 2021-03-09T14:10:31.105+0100 7fc128e05700 10 monclient: tick -5> 2021-03-09T14:10:31.105+0100 7fc128e05700 10 monclient: _check_auth_rotating have uptodate secrets (they expire after 2021-03-09T14:10:01.107451+0100) -4> 2021-03-09T14:10:31.574+0100 7fc1374bf700 10 monclient: handle_auth_request added challenge on 0x55c0b69a8000 -3> 2021-03-09T14:10:32.036+0100 7fc12ca33700 5 prioritycache tune_memory target: 7264711979 mapped: 1708449792 unmapped: 46637056 heap: 1755086848 old mem: 5369698813 new mem: 5369698813 -2> 2021-03-09T14:10:32.106+0100 7fc128e05700 10 monclient: tick -1> 2021-03-09T14:10:32.106+0100 7fc128e05700 10 monclient: _check_auth_rotating have uptodate secrets (they expire after 2021-03-09T14:10:02.107524+0100) 0> 2021-03-09T14:10:32.661+0100 7fc1384c1700 -1 *** Caught signal (Aborted) ** in thread 7fc1384c1700 thread_name:msgr-worker-0 ceph version 15.2.9 (357616cbf726abb779ca75a551e8d02568e15b17) octopus (stable) 1: (()+0x12b20) [0x7fc13cc20b20] 2: (gsignal()+0x10f) [0x7fc13b8847ff] 3: (abort()+0x127) [0x7fc13b86ec35] 4: (()+0x9009b) [0x7fc13c23a09b] 5: (()+0x9653c) [0x7fc13c24053c] 6: (()+0x96597) [0x7fc13c240597] 7: (()+0x967f8) [0x7fc13c2407f8] 8: (ceph::buffer::v15_2_0::create_aligned_in_mempool(unsigned int, unsigned int, int)+0x229) [0x55c0669dce49] 9: (ceph::buffer::v15_2_0::create_aligned(unsigned int, unsigned int)+0x26) [0x55c0669dcf46] 10: (ceph::buffer::v15_2_0::create_small_page_aligned(unsigned int)+0x55) [0x55c0669dd8e5] 11: (ProtocolV1::read_message_data_prepare()+0x368) [0x55c066b78ac8] 12: (ProtocolV1::read_message_middle()+0x130) [0x55c066b78c90] 13: (ProtocolV1::handle_message_front(char*, int)+0x2f4) [0x55c066b79624] 14: (()+0xf72bed) [0x55c066b72bed] 15: (AsyncConnection::process()+0x8a9) [0x55c066b6fa39] 16: (EventCenter::process_events(unsigned int, std::chrono::duration<unsigned long, std::ratio<1l, 1000000000l>
