    Description

      Whenever a CPT lock is taken and some list is traversed, keep the max time the CPT lock is taken. Soft lockups have been observed on several sites. It took a long investigation to understand the reason for the lockups. Keeping statistics on the max length of time a CPT remains locked will allow us to identify these issues quicker.

      Track the load on the different CPTs. This will improve our ability to fine tune CPT configuration.
