I find that some of the toughest bugs to solve are the ones where the undesirable effect has more than one cause.
To be precise it's the kind of situation where the bug can be triggered by 2, 3 or more independent causes, i.e. each cause is sufficient on its own to cause the bug.
Often when attempting to solve a bug like that I'll find one likely cause, address it but because the bug persists, I end up undoing the fix for cause #1, then finding cause #2 and ping ponging between them till I realise that I have to address multiple causes to make the bug go away.
