We have been using Cloudberry Drive (v2.4.2.16) on Windows Server 2016 to copy files to Wasabi cloud storage. At present we've managed to copy almost 1TB of data files to Wasabi. 25% of the files are 50MB in size. The other remaining files are 1KB so that's a lot of files we're copying to Wasabi.

We had observed in Task Manager that Cloudberry Drive service seemed to be consuming a lot of memory. At one point it had 8GB allocated. So we stop/quit the service and re-started it and the memory consumption went back down to normal levels. To be safe, we went into the options > Advanced tab and set the "Limit cache size" to 1GB.

Running for about a week, Windows OS informed us that the system was running low on memory. Opening up the Task Manager, we discovered that Cloudberry had almost consumed 80% of the 30GB of total memory available on that VM. Please note we are using Microsoft Hyper-V for our VMs.

This was completely unexpected. Has anyone else observed the same thing with their CloudBerry Drive service? Our first suspicion was that there was a memory leak in the service, but maybe we haven't configured the Cloudberry Drive settings correctly? Most everything is left at the default setting when we installed CloudBerry Drive with the exception of the "Limit cache size" which we set to 1GB.
