Looks like the spring influx of wildlife has had ramifications on our IFO.  More testing will be done but looks like mice may have contributed to the problem with the whitening chassis.  An opAmp was covered in corrosion and other problems on the board looked like a mouse outhouse.  We have cleaned and disinfected the chassis and are waiting for it to dry before doing more tests.
