these are caused by a SIGSEGV in couchjs, during GC. worker threads are paused, main thread is in the middle of GC. Filed [upstream](https://bugzilla.mozilla.org/show_bug.cgi?id=1896604) but they rightly point out we need to be on a SM supported version for this to be worth looking at. ``` * thread #1, name = 'couchjs', stop reason = signal SIGSEGV * frame #0: 0x000000008321f3a0 libmozjs-91.so`js::gc::MapAlignedPages(unsigned long, unsigned long) + 1232 frame #1: 0x00000000831e56f0 libmozjs-91.so`js::gc::GCRuntime::pickChunk(js::AutoLockGCBgAlloc&) + 132 frame #2: 0x00000000831e54a4 libmozjs-91.so`js::gc::ArenaLists::refillFreeListAndAllocate(js::gc::FreeLists&, js::gc::AllocKind, js::gc::ShouldCheckThresholds) + 308 frame #3: 0x00000000831e4638 libmozjs-91.so`js::jit::JitCode* js::Allocate<js::jit::JitCode, (js::AllowGC)0>(JSContext*) + 128 frame #4: 0x0000000083478618 libmozjs-91.so`js::jit::JitCode* js::jit::JitCode::New<(js::AllowGC)0>(JSContext*, unsigned char*, unsigned int, unsigned int, js::jit::ExecutablePool*, js::jit::CodeKind) + 44 frame #5: 0x00000000834a27c8 libmozjs-91.so`js::jit::Linker::newCode(JSContext*, js::jit::CodeKind) + 284 frame #6: 0x00000000832922c8 libmozjs-91.so`js::jit::BaselineCacheIRCompiler::compile() + 15424 frame #7: 0x000000008329b6e0 libmozjs-91.so`js::jit::AttachBaselineCacheIRStub(JSContext*, js::jit::CacheIRWriter const&, js::jit::CacheKind, JSScript*, js::jit::ICScript*, js::jit::ICFallbackStub*, bool*) + 212 frame #8: 0x00000000832cf2a0 libmozjs-91.so`___lldb_unnamed_symbol30268 + 276 frame #9: 0x00000000832cf070 libmozjs-91.so`js::jit::DoGetPropFallback(JSContext*, js::jit::BaselineFrame*, js::jit::ICFallbackStub*, JS::MutableHandle<JS::Value>, JS::MutableHandle<JS::Value>) + 444 frame #10: 0x000014c25c2ea554 ``` I will see if I can track down what changed back in December, that this stopped working. couchjs is not exactly a fast-moving target. -- This is an automated message from the Apache Git Service.
