Chapter 13 Troubleshooting
Scheduled Resource Intensive Tasks
Scheduling multiple resource intensive tasks at the same time can adversely impact server performance and
affect application performance.
Symptom
Resource-intense scheduled tasks impact performance at certain times.
Cause
Two or more resource-intense processes run simultaneously or one process performs actions that increase the
load on vCenter Server Heartbeat by triggering additional and sometimes unnecessary replication traffic.
Examples: processes such as backups, database maintenance tasks, disk defragmentation, or scheduled virus
scans.
Resolution
Schedule operations so that they do not overlap and schedule them outside regular working hours, when
fewer users are accessing the protected application and consequently less load on the server.
