7.7 bug? - BaseX-Talk - mailman.uni-konstanz.de

6 Sep 2013


      HI all,
I'm getting this bug, which seems to happen when I have two clients talking to the db at the same time, one via the command line, and one through a socket connection using the PHP API. After this error, the data appears to be corrupt and the only solution is to quit the server and all clients, restart, and drop the database. Wasn't having this problem under the same usage with 7.0.2.
THanks,
-BB
Here's the error message:
