Resolución
WORKAROUND #1
Disable the OS collections for all of the instances except for one.
WORKAROUND #2Disable the "File System IO" collection to stop the IOSTAT command.
WORKAROUND #3The VMSTAT command is run by a collection that combines OS and JDBC collection information so this is slightly more problematic to disable.
WORKAROUND #4
Revoke the permission for the OS user to execute the IOSTAT/VMSTAT commands.
Doing this would cause the Agent logs to get errors printed into them; however, it would also stop these commands from executing without disabling the entire OS collection.
