Abstract

A system to check for memory leaks in storage may include a data processing application executing via a computer processor, and storage to store data generated by the data processing application. The system may also include a monitor executing via the computer processor that checks the storage over different time intervals in order to identify a particular sized memory leak in the storage based upon each time interval'"'"'s length.

Claims

1. A system comprising:

a data processing application executing via a computer processor;

storage to store data generated by said data processing application; and

a monitor executing via the computer processor that checks said storage over different time intervals in order to identify a particular sized memory leak in said storage based upon each time interval'"'"'s length.

2. The system of claim 1 wherein said monitor uses at least one of a short time interval to identify large sized memory leaks, an intermediate time interval to identify medium sized memory leaks, and a long time interval to identify small sized memory leaks.

3. The system of claim 1 wherein said monitor collects historical data for comparison with future data of a respective time interval to determine if a memory leak exists.

4. The system of claim 1 wherein said monitor checks are based upon a threshold for said storage being used.

5. The system of claim 4 wherein said monitor enables the threshold to be configurable.

6. The system of claim 4 wherein said storage comprises at least one of random access memory, swap space, real memory, and virtual memory.

7. The system of claim 6 wherein said monitor checks that at least one of a total amount of free space in the swap space is above its respective threshold and that total swap size is below its respective threshold.

8. The system of claim 6 wherein said monitor reports an error when a first threshold is crossed, and terminates said data processing application'"'"'s process when a second threshold is crossed.

9. The system of claim 4 wherein the threshold comprises a percentage of said storage.

10. The system of claim 4 wherein the threshold is tailored for each process of said data processing application.

11. A method comprising:

storing data generated by a data processing application in computer readable memory; and

checking, via a monitor executed by at least one computer processor, the computer readable memory over different time intervals in order to identify a particular sized memory leak in the computer readable memory based upon each time interval'"'"'s length.

12. The method of claim 11 further comprising using at least one of a short time interval to identify large sized memory leaks, an intermediate time interval to identify medium sized memory leaks, and a long time interval to identify small sized memory leaks.

13. The method of claim 11 further comprising collecting historical data for comparison with future data of a respective time interval to determine if a memory leak exists.

14. The method of claim 11 further comprising checking that at least one of a total amount of free space in a swap space is above its respective threshold and that total swap size is above its respective threshold.

15. The method of claim 11 further comprising reporting an error when a first threshold is crossed, and terminating the data processing application'"'"'s process when a second threshold is crossed.

16. The method of claim 11 further comprising tailoring for each process of the data processing application a threshold.

17. A computer program product embodied in a computer readable storage medium comprising:

computer readable program codes coupled to the computer readable storage medium to check storage for memory leaks, the computer readable program codes configured to cause the program to;

store data generated by a data processing application in storage; and

check with a monitor the storage over different time intervals in order to identify a particular sized memory leak in the storage based upon each time interval'"'"'s length.

18. The computer program product of claim 17 further comprising program code configured to:

use at least one of a short time interval to identify large sized memory leaks, an intermediate time interval to identify medium sized memory leaks, and a long time interval to identify small sized memory leaks.

19. The computer program product of claim 17 further comprising program code configured to:

collect historical data for comparison with future data of a respective time interval to determine if a memory leak exists.

20. The computer program product of claim 17 further comprising program code configured to:

check that at least one of a total amount of free space in a swap space is above its respective threshold and that total swap size is above its respective threshold.
