The task stack traces dumped from jl_print_task_backtraces() in prod seem to sometimes fail to decode.
The code in our custom (RAI) codebase, as users of Julia, seems to have 3 possible outputs in the stack traces:
- It is decoded correctly. For example:
macro expansion at /nix/store/p6p0vcy5fcmz4fw2wp368b4pasiri003-rai-server-binary-linux/rai- server/packages/ThreadingUtils/src/ThreadingUtils.jl:182 [inlined] - It shows up as
unknown function. For example:unknown function (ip: 0x7f09a272436f) - It shows up as
jfptr_YY.*. For example:jfptr_YY.1_301099 at /nix/store/p6p0vcy5fcmz4fw2wp368b4pasiri003-rai-server-binary-linux/rai-server/rai-server/lib/julia/sys.so (unknown line)
For example, here are some stacks I see in the logs:
