Hi,
We've been having this persistent issue with our webDAV connection to XML Oxygen.
How to reproduce: 1. Create a DB with 200/300 documents. 2. Create a webDAV connection to the DB within an XML Oxygen project. 3. Right click the DB from the project > Find/Replace in files, and type a keyword to search for for all files *.xml 4. Run the search 3 to 5 times. Until you notice the error.
The error doesn't always occur, but I'd be surprised if you didn't see it after 3 to 5 try.
Example 500 error: System ID: http://admin@localhost :8984/webdav/en-us/topics/widget-bookmark.xml
Severity: error Description: 500 Internal Server Error for: http://localhost:8984/webdav/en-us/topics/widget-bookmark.xml
In the case of a 500 error, you need to restart the server to be able to open or search files from the DB again.
Can anything be done to improve the situation?
Regards,
France
Hi France,
The error doesn't always occur, but I'd be surprised if you didn't see it after 3 to 5 try.
For testing, I created a database with 500 documents (input appr. 80 MB) and another one with 20,000 documents (1 GB). Unfortunately (or maybe good for us?), I didn't manage to crash the WebDAV driver, using the latest snapshot (I didn't try any earlier version); maybe someone does?
Can you find some additional information on the error in the log files or on stderr?

Took me 6 searches on a DB with 272 documents to crash. I found a lot of these in the log:

We've had this error for the last 2 years and the snapshot we have is very stable, so we are resisting the upgrade. Are there reasons to believe that this long standing issue would have been resolved since BaseX 8.0 beta 1e3f811?

Hi France,
The error doesn't always occur, but I'd be surprised if you didn't
see
it after 3 to 5 try.
For testing, I created a database with 500 documents (input appr. 80 MB) and another one with 20,000 documents (1 GB). Unfortunately (or maybe good for us?), I didn't manage to crash the WebDAV driver, using the latest snapshot (I didn't try any earlier version); maybe someone does?
Can you find some additional information on the error in the log files or on stderr?
