This looks like an ocis issue to me. @kulmann @butonic what do you think moving to ocis?

@saw-jan please skip those tests for now for ocis and add a todo here to unskip the tests again

[saw-jan]

[QA] TODO:

• unskip the tests related to this issue (skipped in [tests-only][full-ci] Skip tests on oCIS related to batch request web#6828)

[kobergj]

Reason is the flock issue. Closing this in favor of #3757
