Hi,

I am querying 60 DBs one after the other, depend on the results from every DB, I am getting ad different DB errors, every time on different DB, sometime on one, sometime on few.
I I query only 10 DBs for example, I get no errors.

The error is:

Error: {gen_server,call,
{get_index,
{couch_mrview_index,
{mrst,
