[CWB] Can't generate text-by-text freq lists?

[Arthur Wang]

Hi,

These days I installed a 1 million word corpus in CQPweb (v3.2.26) and 
its metadata (tsv), and then told CQPweb to auto generate the freq 
lists, everything looked fine.

But then I found that the text freq lists were not actually generated - 
"Distribution" shows zero for "Hits in category", "Dispersion" and 
"Frequency", and I can't search by category at all. I check my metadata 
file, it's perfectly ok.

Then I tried generating the text/category freq lists manually, no luck 
either.

What are the possible reasons for text freq lists to fail to be 
generated? Thanks for any clue.
