Well, I'm not 100% sure, but I recently switched for MLDBM and got this
problem too. Here is what I found, and did to remedy the situation :
It *seemed* to me that the physical MLDBM repository was not physically created
until I actually wrote something into it, eventhough it was reported as
correctly open RW.
So, any ends of my application trying to fetch value during this
transcient stage got this kind of error (I do not remember
precisely which one I got, but very close indeed).
I solved the problem by doing an awful trick on each RW opening, such as
:
eval {
tie %hash, "MLDBM::Sync", $storage, O_RDWR | O_CREAT, 0660;
$hash{'__DuMmY__'} = 'OK';
delete $hash{'__DuMmY__'};
};
That solved the problem in the midtime, waiting for something
much better...
