-44087 and other CAN errors

Hi people!

We're using the CAN Bus this year (as well as last year), but we're having some weird issues.

When we try to drive the robot, the drive train motors stutter a bit. Almost like a lag of sorts. We have a total of 7 Jags in a CAN bus and all have the latest firmware. We are NOT using the ClassMate, but rather a old Lenovo laptop (still low-end, but should be fine for driving)

We are getting errors codes -44061 and -44087 in the driver station. The driver station log file is attached (just running teleop).

We tried using both 5GHz and 2.4GHz connections, same problem either way. We DID notice that, on the dashboard, if we disabled the camera, the stuttering is lessened, but still not perfect (with the camera on it's a bit worse).

This is pretty late in the build season, but hopefully we can figure this problem out :-)

Thanks!
