They have all come up on this list before, though they have not all been 
fully described here.

1) The Carbon version of Summary running under OS X will sometimes see 
log files as being larger than 2 Gig in size, even though they are much 
smaller than that, at which point it gives up on reading them. Check for 
log files that appear to be 2 Gig in size in Summary's Log Files report. 
This is the problem you (Jeff Logan) were having.

2) OS X does not allocate enough vnodes (an internal system resource) for 
some situations. Running out of vnodes can cause a great number of 
different errors, ranging from the inability to open log files all the 
way up to kernel panics. This causes problems with both versions of 
Summary running under OS X, and with any other applications running on 
the machine. Normally a vnode problem will get worse the longer it has 
been since the machine was rebooted.

3) OS X will not always be able to open a file, even if there is nothing 
at all wrong with the file, there are plenty of vnodes available, and the 
machine has been rebooted recently. This normally shows up in Summary as 
"Error opening log file" messages in Summary's log file 
(./data/summary.log). This appears to be very rare, less than once in 
several thousand log files, and is often hard to distinguish from the 
vnode problem, a mild case of which has the same symptoms.
