Memory Leak in Lightroom CC and Helper

  • Updated 10 months ago
On my Mac, I'm trying to import 180,000+ images, however, I can only import about 10-20K or so at a time because Lightroom CC memory grows to consume all available memory. When that happens, I have to shutdown Lightroom and restart the import. I've been keeping Activity Monitor up while importing and I would expect memory usage to reach a stable plateau at some point. It never does. It just grows and grows until nothing is left and it stops responding.

So, I had a memory leak that sounds similar. I thought it had been stomped on by a programmer, but you never know -- these bugs can have a life of their own.

If it is related to mine, I would suggest importing and not building any previews if possible, then build standard previews, then (if desired) build 1:1 previews. It might be the same with smart previews, but I didn't test that case. In my case of 2 years ago, the problem only occurred (AFAICT) when trying to build two kinds of previews simultaneously.
