(There are other messages possible. It is just an example.) The same sort of point would go for Dan K. for the LX2K/CEX7 context. If such messages are produced, it might help give more of a hint what is going on. If none are produced, that may have implications for what the code sequence was that might also help identifying the issue(s). --=20 You are receiving this mail because: You are the assignee for the bug.=
