----------------
So, can we see it? :)
Maybe there is just some bug in logic, or a false deadlock report? Is it actually a legit report?
If it is a true report, then we should consider increasing the limit (and then we don't need to remove the CHECK). If it is a false report, then we need to fix something (and again no need to remove the CHECK, let it catch more bugs).
