Unable to fork in Msys2

[pavelkryukov]

Hi

We experience random errors in forks occurred during msys64 builds today:

      1 [main] make 2196 fork: child -1 - forked process 3928 died unexpectedly, retry 0, exit code 0xC0000005, errno 11
make[2]: fork: Resource temporarily unavailable

@pavelkryukov this can be connected to recent build worker images update which includes MSYS2 updates.

As a temporary workaround please try to use Previous Visual Studio 2017 image.

Let us know if this help, but even if yes, do not close the issue, we need to root cause and fix it (or have a workaround) it before next build worker image update (when current image becomes "Previous").

Thanks, it helps.

I still see the failure in new image. Additionally, I noticed that it does not happen if "build" is set to "msvc", only "g++" builds are failing (we use MSys in both)

Fixed in the image of last week
