Hi! Our customer are from time to time experiencing trouble with updating product. At this time it works fine for us. The execption in the log is: ``` IWebLog exception 'An error occurred while updating the entries.

It can be some corrupted data on relationship links on some products. Does this happen from BO or on integration processes? ---

Hi! In the BO and so far we cannot reproduce, meaning it works for us at the same time the customer has problem, but I have seen it on the customers machine and the exception is there. ---

Do you test on same server as customer? If not on same server, then another possibility is that the cache might be corrupt/invalid/behind on the server the customer uses. ---

Yes Martin is correct, restart the site and try it out and if it still throws exception then create a ticket so we can examine the customer DB. ---

Yes, they only have on server so we are using the same server when they get the error and we don’t. Ok, I will restart and see what happens ---

The error comes from a link between the base product and a product list. Do they use dynamic product lists that may add or remove the product from the product list on the same time when the customer are saving. Does the history for the product indicate any other update of the product in the same time-frame as the error occur? ---

They have a lot of product lists but only static, they are not using any dynamic lists. ---
