The default value for unspecified field 'interval' for the iCall periodic handler configuration item might cause system instability, and consume 100% CPU.
The system might become unstable and cause daemon restarting.
Not defining the 'interval' value on creation, or modifying the value to '0' using vCMP.
Specify an interval value of '1' or greater for all iCall periodic handlers
In cases in which no value is specified for interval' for the iCall periodic handler configuration, or if the value specified is '0' (zero), a negative value, or greater than the maximum '4294967295 value', the system displays a valid error, so no system instability can occur. Note that upgrades in which the interval value is '0', the system modifies that value to '1'.
