In a customer’s CRM2016 On-Premise cluster deployment the CRM Asynchronous Processing Service gets stuck in a more or less periodic interval. Sounds like kind of leakage somewhere … So I started with problem analysis by crunching Windows Server event logs and CRM systemjob logs into co-related timeseries data, visualizing them and then considering typical suspects like auditing CRM maintenance job configurations, custom-developed CRM processes and general MSSQL database state. While doing so I noticed several log entries for a CRM maintenance task with type code “61“. The fact that this task type is not documented in any of the official sources nor Google did yield some search results made me curious.
