Can a TIM ever display zero SSL decode failure errors?

A customer has a large amount of SSL decode failures. In their case, TIM SSL server statistics since 12 A.M. Monday show 229,624 connections with 16,672 decode failures (7%) and zero for unsupported cipher suites.  They want to know if there can be any connections with zero decode errors?




Given that decode failures can be caused while the packet is moving through the network, due to ssl cipher suites, dirty traffic, empty TCP packets, and other situations, 7% is not beyond a normal expectation.  It would be unexpected to ever see zero unless the network is underutilized.
