Problem Statement/Rationale
Last night I left a MongoSH open and connected to a local MongoDB instance running an infinite loop running a simple find:
Enterprise replset [direct: primary] locust_read_write_load> while (true) { var a = db.load.find({shardKey: 349601785}); }
This morning when I logged back into the workstation, I see that it has crashed with the following stack trace (I have the core dump uploaded to this Amfora Portal):
<--- Last few GCs ---> [476978:0x3d8f1cd0] 1389689 ms: Scavenge 3873.6 (4125.2) -> 3861.2 (4125.2) MB, 13.32 / 2.45 ms (average mu = 0.329, current mu = 0.326) task; [476978:0x3d8f1cd0] 1389795 ms: Scavenge 3875.4 (4126.3) -> 3863.0 (4126.3) MB, 15.33 / 2.42 ms (average mu = 0.329, current mu = 0.326) task; [476978:0x3d8f1cd0] 1389895 ms: Scavenge 3876.8 (4127.7) -> 3864.7 (4127.7) MB, 15.05 / 2.40 ms (average mu = 0.329, current mu = 0.326) task; <--- JS stacktrace ---> FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory 1: 0xd1e754 node::Abort() [mongosh] 2: 0xc1a6a0 [mongosh] 3: 0xf1cb88 v8::Utils::ReportOOMFailure(v8::internal::Isolate*, char const*, v8::OOMDetails const&) [mongosh] 4: 0xf1cd60 v8::internal::V8::FatalProcessOutOfMemory(v8::internal::Isolate*, char const*, v8::OOMDetails const&) [mongosh] 5: 0x11198a0 v8::internal::Heap::CheckIneffectiveMarkCompact(unsigned long, double) [mongosh] 6: 0x1119c98 v8::internal::Heap::RecomputeLimits(v8::internal::GarbageCollector) [mongosh] 7: 0x112eaf8 v8::internal::Heap::PerformGarbageCollection(v8::internal::GarbageCollector, v8::internal::GarbageCollectionReason, char const*) [mongosh] 8: 0x112f06c v8::internal::Heap::CollectGarbage(v8::internal::AllocationSpace, v8::internal::GarbageCollectionReason, v8::GCCallbackFlags) [mongosh] 9: 0x1179580 v8::internal::MinorGCJob::Task::RunInternal() [mongosh] 10: 0xd860fc [mongosh] 11: 0xd89530 node::PerIsolatePlatformData::FlushForegroundTasksInternal() [mongosh] 12: 0x18121cc [mongosh] 13: 0x182714c [mongosh] 14: 0x1812fcc uv_run [mongosh] 15: 0xc4a444 main [mongosh] 16: 0xffff9a6e73fc [/lib/aarch64-linux-gnu/libc.so.6] 17: 0xffff9a6e74cc __libc_start_main [/lib/aarch64-linux-gnu/libc.so.6] 18: 0xc52390 [mongosh] Aborted (core dumped)
Steps to Reproduce
Leave MongoSH running for very long time (don't know how long) with the following operation:
Enterprise replset [direct: primary] locust_read_write_load> while (true) { var a = db.load.find({shardKey: 349601785}); }
