thread 'actix-rt|system:0|arbiter:2' has overflowed its stack

[charlieglnp]

SQLPage has started crashing on me with this error, using the prebuilt windows binary running on Windows 11 accessing an SQL Server 2019 database:
thread 'actix-rt|system:0|arbiter:2' has overflowed its stack

(or no error at all.)

It seems to happen consistently with one particular file which calls a stored proc using EXECUTE, which itself EXECUTEs a number of other stored procs - commenting it out and it seems okay. But it also happens on and off (unpredictably) with simple ones, and happens with versions 0.38.0, 0.37.1 and 0.35.2 (I haven't tested with others). I haven't had any problems with these particular operations (or any!) previously in the last 1+ year of weekly use but we have recently been upgraded to Windows 11 and I'm wondering if that's related.

I've also managed to trigger with 0.35.2:
thread 'tokio-runtime-worker' has overflowed its stack

I've tried increasing the stack size with e.g. set RUST_MIN_STACK=33554432 with no affect but that's the limit of my rust troubleshooting knowledge!

Is there anything I can do to help narrow down what's causing this?

Hello and thank you for taking the time to report this !

Could you please try to create a minimal reproduction ? Create a minimal database and sql file that reliably cause a stack overflow and post them here.

It would also help if you could set RUST_LOG=trace RUST_BACKTRACE=full and post the full sqlpage logs from before the crash.

Tanks!

Hmm, okay, now I can't reproduce this at all!

This definitely suggests to me its a problem my end - clutching at straws but there were some Windows 11 updates a couple of days before this happened and then some after; I've also physically moved the computer and that makes me wonder whether its a hardware issue (eg I've dislodged the ram). I'll close this for now.

You could still run sqlpage with RUST_LOG=trace for some time so that if it happens again you'll be ready to make a detailed report.
