Description (partial)

ESD restarts when the number of  CAPI messages RX/TX exceeds 2^31 - 1  (2147483647).
The problem is because of incorrect signed/unsigned usage in CAPI code.

When any process in Spirit based architecture using CAPI sends or receives CAPI messages greater than
2^31 this problem will present itself.
This usually seen on systems that have been running for a long time.
