Unable to acquire lock after 90 seconds

[kcravi]

Hello

We are using Jaspersoft 6.1_5.1.0.26.   When I tried to reports after filling out input controls, I get the message "Unable to acquire lock after 90 seconds".   I filled out multiple input controls and expected number rows are from the datbase between 300 to 500. So result data set is not huge.  I am not sure what this error message means and keeps appearing intermittenly.  

Can you please help resolve this issue

Thanks

It's a problem with your database and application server settings. Since you didn't provide any information about your application server and about the database you're using, recommend that you google.
