US 2008/0178189 A1 · Efficient detection of sources of increasing memory consumption

Abstract

A method for detecting increasing memory consumption of an application program is provided. The method includes monitoring memory consumption at an allocation site and updating an allocation site threshold value each time the memory consumption increases. The method further includes increasing a growth period counter each time the allocation site threshold value increases in a current time period. The method yet also includes comparing the growth period counter to a growth threshold. The method yet further includes, if the growth period counter is greater or equal to the growth threshold, computing an elapse time, which is the time between the current time period and a previous growth period. The method moreover includes comparing the elapse time to a time threshold. The method in addition includes, if the elapse time is less than the time threshold, reporting the allocation site as a potential source of the increasing memory consumption.

Dependent claims

A method for detecting increasing memory consumption of an application program in a computer system, comprising:

monitoring memory consumption at an allocation site, said allocation site being a location in said application program where a new object is created;
updating an allocation site threshold value each time said memory consumption at said allocation site increases;
splitting an application execution time into time periods;
increasing a growth period counter each time said allocation site threshold value increases for said allocation site in a current time period;
comparing said growth period counter to a growth threshold;
if said growth period counter is greater or equal to said growth threshold, computing an elapse time, said elapse time being a difference between a current period and a previous growth period;
comparing said elapse time to a time threshold;
and
if said elapse time is less than said time threshold, reporting said allocation site as a potential source of said increasing memory consumption.
