I have a Multilink with two T1's in the bundle. Been having a weird issue. The multilink will work fine for a few days. Then I will just start dropping a lot of packets. I have contacted my MPLS provider. They see no issue with the circuit. While the multilink is dropping packets I see no errors on either serial interface. I also do not see any errors on the show controller t1. I can take a one of the serial interfaces out of the multilink, then add it back to the bundle the issue will go away for a few days then come back. Been happening for several weeks now. Start dropping packets take serial link out of bundle add it back problem goes away then comes back few days later. I have taken off all qos for trouble shooting. Have the same issue with or without qos.
