Little memory leak?

[Paul Matthijsse]

Hello, sometimes I’m running low on memory when using ART. Restarting the application solves this. I did some testing to find out where this could come from, but couldn’t find any tool that causes this. I noticed the following though, on a 6 years old simple pc (AMD quad-core, 8GB RAM, Xubuntu 18.04 LTS).

I reboot the pc and start only one application, Geany. Free memory according to GKrellM: 7370 MB.

I start ART with last visited folder. Free mem: 7089.

Now I open 5 NEFs and close them. I repeat this 6 times. I noted the free memory after closing them:

• 6437
• 6038
• 5873
• 5744
• 5490
• 5371

So there’s ~1700MB gone after this operation. Closing ART gives me 7372MB free, as before opening ART.

Not a big deal but perhaps it’s easy to find what causes this.

Regards, Paul.

are you compiling yourself? If so, are you using tcmalloc?

[Paul Matthijsse]

Yes I do compile myself with the following 3 commands (I’m not a specialist in compile options, if it works for me it’s OK):

• cmake -DCMAKE_BUILD_TYPE=Release
• make -j5
• sudo make install

try installing tcmalloc if you haven't already (usually the package is called gperftools)

Hello.

on my system as well, Art is quickly very memory-hungry (Manjaro linux). After processing a photo with a few local layers, I quickly go up to 6-7 GB of memory used.
I compile Art with build-art, and I'm on the latest version. Tcmalloc is installed on my computer.

Hello, I installed that package, do I need to set a compilation flag ?
