Hi Oliver,
I tried both GUI mode and terminal client. I get the same error there. And also Map Visualization worked fine for the same collection before I created indexes. Don't you have the same problem in terminal mode? How big is your collection then (number of files and size in MB)?
Best regards, Ivan

Hi Ivan,
I used to have the same problem. If you are working with the GUI mode, try to close the Map Visualization. (Open another smaller DB, close the Visualization, and try to open your Database again). That worked fine for me.

Hi,
I have a database collection with over 17000 documents (about 190MB in total). Everything worked fine until I created text and attribute indexes to improve performance. Now I cannot open database and perform any operation with it because I get 'Error: Out of Main Memory'. Setting "intparse on" doesn't help. I've increased Xmx value up to 2560m (maximum value for my system), it doesn't help too. Is there any way to fix it? Could you provide an approximate size of memory that is required for text and attribute indexes depending on the size of the database? Is there any possibility for me to use indexes on current system? Thanks in advance!

Ivan,
hm, 190 MB sounds like a pretty small collection; 2.5 GB RAM should suffice to process 10 times the data and more. Have you tried version 6.2.9 of BaseX? Could you please check out the debugging flag on command line? Try sth. like:
java -cp basex.jar org.basex.BaseX -d -c "create db ...."
Thanks, Christian

Dear Andreas,
I've started the server with the following command: java -Xms256m -Xmx2560m -XX:MaxPermSize=256m -cp basex.jar org.basex.BaseXServer -d
Then I've tried to 'open database' in basex client.
Finally I've got the following exception: BaseX 6.3 [Server] Server was started. java.util.Arrays.copyOf(Arrays.java:2834) org.basex.util.IntList.add(IntList.java:53) org.basex.data.Data.doc(Data.java:195) org.basex.core.Context.update(Context.java:126) org.basex.core.Context.openDB(Context.java:108) org.basex.core.cmd.Open.run(Open.java:35) org.basex.core.Command.run(Command.java:236) org.basex.core.Command.exec(Command.java:218) org.basex.core.Command.execute(Command.java:66) org.basex.server.ServerProcess.run(ServerProcess.java:161)
Memory usage of the server java process reaches 1.6GB (I was monitoring it visually using 'top' linux command so real usage might have been even higher).

Dear Andreas,
It worked fine as soon as I created the database with the newest version. But I'd like to be confident of BaseX that I won't lose my data as it happened for the version 6.1.

the database corruption you reported was most probably caused by an evil bug in the XQuery Update code that we were able to fix in version 6.2.8. It destroyed parts of the index structure, leading to reads on empty DB pages. The stack trace you provided is a result of that.
So I think the problem shouldn't happen again :-).
