We have a scenario with 3 producers, we isolate one of them for a long time (expecting it to abort on RequestTimeout) and then creating another producer to prove mdsal still works.

But recently (in a Sandbox run which failed to archive logs) I have seen [0] the error below. If the isolated producer is still alive, the suite would detect that anyway. Using different prefix will avoid having to parse the new error.
