Message 'Corrupted Data File' with ID 150 reported in the event viewer

This message is reported in the event viewer:

  Corrupted Data File deleted     cstat     cstatd     150

What does it mean?

 

The statistic cook daemon uses several check routines to keep the consistence of statistics files. If a file is erroneous, the daemon will delete this file and Event ID 150 will be displayed in the event viewer.

The question is: Why are statistics files corrupted? There are only two possibilities:

    - The box was shut down (power off) while writing the statistics into a file.
    - Either harddisk or filesystem has an error.

1) The box was shut down (power off) while writing the statistics into a file.

    - Check CPU and MEM statistics for irregularities in the records.
    - Check Status GUI in phiona for uptime.

2) Either harddisk or filesystem has an error.

    - Consult "Log" > "Box" > "System" > "klogd.log" for harddisk error messages.
    - Consult "Log" > "Box" > "Statistic" > "cstatd.log" for "clock skew" messages (many entries).
    - If you use an IDE harddisk use command "smartctrl" on command line for checking purpose
     smartctl -a /dev/hda
