New subject: Runtime Exception

26 Apr 2016


      Dear Mansi,
you could try to run the INSPECT command on the affected database, or all
databases, in order to find out if your database has gone corrupt. Did you
repeatedly come across this error?
Best,
Christian

Hello,
My current BaseXDB is at 920GB, with ~230 databases... I run jetty server
visa basexhttp script with giving it explicit 30GB of RAM. While trying to
access a query, thru REST api via XQUERY, I get below error.
...
