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
ToggleGlobalReadsin safety mode to reduce test failures. This change would also help confirm that this is the only operation susceptible to the hanging behavior.Fixes: #160293
Release note: None
