The ISTATs daemon processes data in the archive.tm2 data file, residing on the disk, which tracks configuration changes for istats data. The processing can become inefficient when the file grows large, causing the ISTATs daemon to use excessive CPU.
The archive.tm2 file to grow too large. The control plane is starved of CPU for other operations.
Many istats configuration changes over time.
Remove the /var/tmstat2/blade/archive.tm2 file from disk.
