If this doesn’t yield a reproduction in due time, you could try under race (add --race flag) or adjust the level of parallelism:

PKG=./pkg/what/which
TEST=TestFoo
P=100
./dev test --stress $PKG --filter $TEST [--race] --cpus 20 --jobs $P --local_resources=cpu=$P --jobs 20local_resources=memory=HOST_RAM 

Other Notes:

• To print the full logs of the failed test trial, add --show-logs to your test cmd. Run ./dev test --help to see this option. (The CRDB logs are default saved to a temp dir, but the path to that dir is currently broken).

• If you’re trying to reproduce an instance of a slow or hanging test, add a per trial timeout (i.e. fail if a test trial takes longer than 5 minutes), add --test-args='-test.timeout 5m' to your test cmd. test-args are passed directly to go test whose binary is executed for every trial in stress; therefore, --test-args can be treated as ‘per trial’ args.

• Build tags are passed like this (note the -- args separator):

  ./dev test --stress $PKG --filter $TEST -- --define gotags=bazel,gss,deadlock
