Hello,


currently i've got a Problem in an WebApi Project and i don't have any clue 
where it comes from.

It appears since i updated to .Net Prevodier > 5.0.0.0.

Currently I am using .NetProvider 5.0.5.0



I'm using ninject to create one DbContext per Request.

Sometimes I am getting the following exception after 1 hour, after 10 hours, 
after a week.



Exception occured: System.Data.Entity.Core.EntityCommandExecutionException: An 
error occurred while executing the command definition. See the inner exception 
for details. ---> FirebirdSql.Data.FirebirdClient.FbException: invalid request 
BLR at offset 1094 context already in use (BLR error) ---> 
FirebirdSql.Data.Common.IscException: invalid request BLR at offset 1094 
context already in use (BLR error)
