I have 3 Serial interfaces setup in a multilink configuration. The Multilink interface receive a packet error for almost every input packet. The CRC error counts are almost the same count also. I've checked each individual Serial interface and they show NO errors.
In addition, my Multilink interface availability is constantly 128/255. I will post run-configs and interface status. Thanks in advance for any help.

Which exact IOS are you running ?

Also...I was researching and Cisco's Output Interpreter said that timing could be a problem. Below is the status of the 3 T1 controllers:

All seems fine.
Can you try, for example, 12.4(3j) ?

Unfortunately no. The router is an old 3660 and would need a memory upgrade first.
