Integer values returned by a number of WMI queries were handled incorrectly, squeezing 64 bit integers into 32 bit representation. This lead to sporadical erroneous results for a number of agent sections / checks. Potentially affected were at least the checks wmi_cpuload and ps, but basically any checks using information provided by WMI. The symptoms of this may have been varying across different checks.
