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.</p> <p>Track the load on the different CPTs. This will improve our ability to fine tune CPT configuration.</p> LU-14041
