[CWB] Adding metadata from XML

[mansur]

Hello!

During the last few days I have a very interesting problem:
1. I compile (index) several small corpora with cwb utilities and generate
registry files.
2. I add these corpora to the CQPweb.
3. I choose adding metadata from XML, select the necessary fields and click
"Create metadata table from XML using the settings above" button without
running frequency-list setup. And a small box pops up about the task being
processed. And it doesn't end, lasts forever. Apache web-server (httpd
process) starts to consume 100% CPU time (1 core). It doesn't give any
errors, though I tried to enable debug messages in the config file.

I tried to reinstall the system, and used different revisions of CQPweb and
CWB that were released during last year: something around 1400-1559. The
most stable ones here as I understand are trunc for cwb and 3.2-latest for
CQPweb (3.2.42 if I remember it correctly).

Today I found out a detail that maybe could help to locate the source of
the problem: after adding a corpus to the CQPweb, but before trying to add
metadata if I try to make a search query, then adding metadata works well.
I understand that search queries don't work before adding metadata and it
gives an error, but after that I can easily add metadata without any
problems.

Could you, please, share your opinion about it? How can I fix it or
investigate further to find the exact reason? Maybe it is a bug?

With best wishes,
Mansur
