Severity: 2-Critical


If an error occurs while statsd is reading a file that contains performance data, certain control-plane processes may wait for each other indefinitely. In some instances, error messages about files in the /var/rrd directory may appear in /var/log/ltm.


Attempts to issue commands using "tmsh" may hang up. No "qkview" datasets can be successfully generated.


Errors occur when performance-monitoring processes attempt to read files in the BIG-IP's internal Round-Robin Database.


If damaged data files in /var/rrd can be identified, delete them and run "bigstart restart statsd".
