Memory usage of a process increases while taking a dump, using procdump. Is this even possible?

625 views Asked by At

Good afternoon,
In my company regularly we are dealing with memory leaks, and therefore every installation has a procdump installed, in order to be able to take memory dump for investigation purposes.

Now my customer is complaining about a process, which is normally running at ±500Mb, going to +3Gb in memory usage.

I asked the customer to take a dump, using procdump, which is normal procedure, but the customer answers that the launch of the procdump initiates a memory usage towards 3Gb, making the dump unusable.

Is this even possible? How can a process like procdump increase the memory usage of a process, while taking the dump (and how can this be avoided)?

Thanks in advance
Dominique

No, it seems not to be possible, but there might be catches: in my particular case, our customers monitor memory usage of processes, one time with and another time without shared data (like pagefile usage).

If such a question ever pops up, always verify if the user is monitoring the correct memory usage.

@Raymond: thanks for your quick replies and sorry for the inconvenience
