See CI Run And another CI Smoke Run

This is the first time we've seen this error. So not sure how prevalent.

Expected or desired behavior:

Kallichore to start up

Were there any error messages in the UI, Output panel, or Developer Tools console?

I also ran into this error today on Ubuntu, so it appears to not be isolated to Windows.

jmcphers commented 1 week ago

@midleman Did you see this error interactively, or in a smoke test run? If the latter, could you link it?

(so far I've been unable to reproduce on Windows)

midleman commented 1 week ago

In a smoke test run, but it's on my branch, let me grab the logs ...

jonvanausdeln commented 1 week ago

Sorry.. I got confused looking at failures.. this one was on Ubuntu 22 (as the CI link correctly points to) ...ignore the windows part

jmcphers commented 1 week ago

This scenario passed in my smoke test run with Kallichore enabled so perhaps this is timing related?

Some notes from an initial look:

2024-11-12 14:49:25.336 [info] Positron Kernel Supervisor activated

Waiting for Kallichore server to start (attempt 16, 1391ms)
Kallichore server did not start after 1599ms

So what's interesting here is that Kallichore starts successfully the first time, but after a project switch the IDE restarts and Kallichore doesn't.
