If for some other reason the istats segment files became corrupted, then istatsd could use excessive CPU.
The high CPU use by istatsd could diminish resources available to other processes causing poor responsiveness for things like tmsh or web management.
The istats segment file became corrupted by some other problem.
Stop istatsd and remove the istats segment files. Then restart istatsd to recreate the segment files. This will cause all statistics in these files to be reset.
Even when there is corruption, istatsd will no longer use an excessive amount of CPU.
