64-bit inn and bitmap weirdness

[Christiaan den Besten]

Hi !

We have recently been starting to compile INN in 64-bit on our (newer) 
64-bit Linux spool servers. Since some time I have noticed we see more and 
more of  ..

It looks likes articles are being 'overwritten' after some period of time or 
something like that. From what we have noticed it looks like postings arrive 
'complete', but after some weeks they get broken, which would imply 
something is writing to the spool file at the wrong place ... which might 
explain the overflows.

Has anybody else noticed the above described scenario and found a fix for it 
? :) The spools are running with 16 cnfs stores of 1.2Tb each ( with INN 
2.4.4: 20070610-snapshot, but older versions from 2005 seem to behave the 
same ... )

bye,
