Hi Saqib,

You need to provide a bit more information than just a dump of an error. When does this happen, etc.? Also, given the nature of the error, you may be better off opening a support case with OutSystems via the Support page.

i am adding database and fruntend servers to timetime. i successfully added QA servers without any error. once i added Pre Production database and fruntend servers it was added but there was error like:

Received Packets Discarded (vmxnet3 Ethernet Adapter) above threshold of 2.00 for more than 1 minutes

Unable to fetch metrics

Memory Usage above threshold of 80.00 for more than 5 minutes
