I want to share a solution for this Filemaker Server warning with you.
Some problems were detected in the WPE COMPONENT: POTENTIAL PROBLEM.
This is a similar warning as the frequently mentioned famous 701 error.
I started received these warning messages by mail from the FMS12 server every 10-15 minutes starting from 05.00.
The strange thing is that FMS12 did not show all of these warnings in its logging.
After contacting the hosting provider it appeared that they replaced a fibre connection to the DC's storage that night until 05.00.
The supportdesk published this message:
"We are experiencing at the moment problems with the storage environment at Datecenter 2.
Therefore, some cloud servers on this location have problems to connect to storage which can cause delay or cancellation of the cloud servers."
The problem was solved and the WPE warnings stopped after they fixed to storage connectivity problem.
So, if you get WPE connection warnings or 701 connection warnings: contact your hosting provider!
