Hi Mansi,
Thanks for the feedback. Errors like this sometime occur if databases are requested from different JVMs at the same time. See e.g. [1] for more information.
Cheers Christian

I did try the inspect command on all databases, which should there are no inconsistencies.I was logging any exceptions, in my java code, in case of errors, and that showed me, which database in particular was in problem, dropping it helped.
This was the first time I saw it. I was worried, DB has grown till the point of not being supported, when I actually panicked.
Thanks,

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.
