Only seeing this on a few hosts so far.

[dw]

Most likely they're 32 bit hosts.. I've quite literally just pushed 0.2.6 to PyPI, it includes a fix :) https://mitogen.readthedocs.io/en/latest/changelog.html#v0-2-6-2019-03-06

Thanks a ton for reporting this anyway! And please let me know if it's still broken for you in 0.2.6.

[opoplawski]

They are x86_64 hosts, but I'll try with 0.2.6

[dw]

In 0.2.6 those fields were forced to be signed 64-bit, so no munging should be required for the thread ID or instance ID (both of which might be negative after IIRC Python applies its hash randomization).

But this hadn't manifested on 64-bit before. Are they Intel machines? It's possible it was pure luck this only turned up on ARM the first time around

[dw]

This might be an entirely different issue -- it's not Latch, it's subprocess. Please don't waste time retesting yet, this looks like something different to what I just said :(

[dw]

It's the process affinity code

[dw]

How many CPUs in the machines that failed?

[opoplawski]

80

Hi Orion,

This is on master. There should be another release within weeks. Apologies for the inconvenience, and please let me know if you have any more issues. Thanks again!
