System.IndexOutOfRangeException

Hello,

I am using Umbraco 4.7.2 in combination with Courier 2.7.2. The cms is working normally but sometimes we get the error shown below (System.IndexOutOfRangeException id38_0_)

. The error dissapears when we recycle the application pool or when we delete the Umbraco.Courier.CacheHandler.V4.dll.

Can anyone look into this problem.

Kind regards,
Frank van Rooijen

I am takeing a closer look at the error and notice it was not possible to execute the sql-connection. I fixed some issues with open connections, but didn't role this to production yet. Looks like this issue is connected to this fix. I will investigate further.

Then finally we recieve the message reported. For this moment it means we have to deinstall courier to get a stable enviorment.
