SQL Server Error 25602, Severity 17 generally indicates issues related to resource limitations or environmental factors that prevent a query or process from executing successfully. These errors typically reflect problems such as insufficient memory, disk space, or other system-level constraints. The specific nature of error 25602, however, tends to be linked to failures in specialized operations, such as database replication workflows, features dependent on external integrations (e.g., availability group actions), distributed partitioning tasks, or certain advanced transactional processes (such as snapshot generation). It can stem from inadequate configuration settings for resources allocated at the OS/system/database level required by SQL Server functionality. 

Check System Resources, since this is a severity-level-17 error, verify if you have adequate hardware resources:  

• Memory Usage: Ensure enough available physical RAM.    
• Disk Space Availability: Confirm sufficient free storage space across all relevant drives.    
• Network Bandwidth: Examine networking bottlenecks and TCP congestion.
