Hi A customer sent me *.CPD files of a vms 5.5 system. He claims that at specific point in time the system was stuck. He found that his page file was full - this, obviously, is the cause for that. This means, I assume, that someone is "eating" the system's virtual memory. I.e. there are some processes that increase their virtual memory usage and they do not free it. How can I find which processes/images are consuming the page file ? What I get from DECPS-PA are the points in time that the page file usage was high. From the performance report I saw some processes with high VA usage at those times. I traced also the dump records of the images those processes invoked at those times and saw that the VA usage increases in time. This seems some evidence of memory leak. I did not see there the accumulated time the image was running - which I need to prove that the image consumes virtual memory. How can I get that ? Can I get from the Performance advisor the size of the pagefile ? Are there other reports that can point at memory leak ? thanks Zvi

>How can I find which processes/images are consuming the page file ? It's no possible directly. But from PSPA graph, you can check which users or images are accumulating VA and how pagefiles are being depleted. Also check heavy pagefaulting users or images. - Kazunori | |||||
