Currently, there is a single kvnemesis operation that executes via SQL: `ToggleGlobalReads`. We have seen this operation get stuck and cause the test to timeout under safety more. The expected behavior is that any stuck operations would time out, but it seems like there is a context cancelation propagation issue, most likely in lib/pq, but not confirmed. This commit disables `ToggleGlobalReads` in safety mode to reduce test failures. This change would also help confirm that this is the only operation susceptible to the hanging behavior. Fixes: cockroachdb#160293 Release note: None

Thanks for opening a backport. Before merging, please confirm that the change does not break backwards compatibility and otherwise complies with the backport policy. Include a brief release justification in the PR description explaining why the backport is appropriate. All backports must be reviewed by the TL for the owning area. While the stricter LTS policy does not yet apply, please exercise judgment and consider gating non-critical changes behind a disabled-by-default feature flag when appropriate. |
