Timeouts on new vm-dartkb-linux-release-x64-abi bot #37630
Description
The vm-dartkb-linux-release-x64-abi bot started to have infra failures caused by timeouts, see for example (vm-dartkb-linux-release-x64-abi/252)[https://ci.chromium.org/p/dart/builders/ci.sandbox/vm-dartkb-linux-release-x64-abi/252].
This can be reproduced locally by:
% tools/gn.py '--mode=release' '--arch=x64' --bytecode
% ninja -C out/ReleaseX64 -j200 -l64 create_sdk_with_abi_versions
% mkdir -p out/ReleaseX64/test/logs
% python tools/test.py -t60 -m release -c dartkb --vm-options "--enable-interpreter --use-abi-version=6" lib_2/collection/hash_map_test

--- Re-run this test:
python tools/test.py -m release -c dartkb -t 60 --vm-options "--enable-interpreter --use-abi-version=6" lib_2/collection/hash_map_test
Done dartkb-vm release_x64 lib_2/collection/hash_map_test: fail
So there seems to be some issue with starting the kernel service.
I'm not quite sure what this bot is testing. @liamappelbe @a-siva maybe you know what's happening here?
