Yes, spurious errors are, sadly, not uncommon with the ZEO tests. I think we get a lot fewer now than we used to. Because the ZEO tests actually start servers, they have lots of non-determinism. Further, when there are failures, they are excruciating to debug. This is why I'm working on a new ZEO implementation that will allow testing without creating separate server processes.

Hi,

Thomas and I fixed a ClientCache bug earlier and when running tests (with --all as supposed) we noticed two different tests failing. One of them was checkConcurrentUpdates2Storages (ZEO / FileStorageConnectionTests) the other we can't remember because we lost it in our terminals buffer.

Unfortunately we could not reproduce either test to fail again and we could not determine any relevance of our changes by looking at the failed code.

Does anybody else experience spurious errors currently?
