It is possible that ndalloc will be updated before nmalloc, in arena_large_ralloc_stats_update(), fix this by reorder those calls. It was found by ClickHouse CI, that periodically hits this assertion [1]. [1]: https://github.com/ClickHouse/ClickHouse/issues/31531 That issue contains lots of examples, with core dump and some gdb output [2]. [2]: https://s3.amazonaws.com/clickhouse-test-reports/34951/96390a9263cb5af3d6e42a84988239c9ae87ce32/stress_test__debug__actions_.html Here you can find binaries for that particular report [3] you need clickhouse debug build [4]. [3]: https://s3.amazonaws.com/clickhouse-builds/34951/96390a9263cb5af3d6e42a84988239c9ae87ce32/clickhouse_build_check_(actions)/report.html [4]: https://s3.amazonaws.com/clickhouse-builds/34951/96390a9263cb5af3d6e42a84988239c9ae87ce32/package_debug/clickhouse Brief info from that report: 2 0x000000002ad6dbfe in arena_stats_merge (tsdn=0x7f2399abdd20, arena=0x7f241ce01080, nthreads=0x7f24e4360958, dss=0x7f24e4360960, dirty_decay_ms=0x7f24e4360968, muzzy_decay_ms=0x7f24e4360970, nactive=0x7f24e4360978, ndirty=0x7f24e43 e4360988, astats=0x7f24e4360998, bstats=0x7f24e4363310, lstats=0x7f24e4364990, estats=0x7f24e4366e50, hpastats=0x7f24e43693a0, secstats=0x7f24e436a020) at ../contrib/jemalloc/src/arena.c:138 ndalloc = 226 nflush = 0 curlextents = 0 nmalloc = 225 nrequests = 0 Here you can see that they differs only by 1.

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://jemalloc.net/
