Hi,

We encountered this error in our Production server for about 10-15mins.

then after that, the error disappears, but we didn't change anything in the production server and database server.

but just in case we experience this kind of error again, What is the cause and how can we solve this problem?

Hi Ruzzel,

Seems like all the DB connections are utilized from pool. Is there any long running query causing this, you can check the outsystems service center


Below are the article with possible reasons of this error and it may help you to figure it out
