A recent update (12.1?) breaks ability to store images on network drives
I have been using Lightroom (on Windows) since 5.x... probably 8 years or so. I use an Ubuntu file server with a RAID 5 array to store my images. Lightroom itself, and its catalog, are local on my Windows 10 laptop. The laptop has a 1000BaseT wired connection via its docking station. The file server is also 1000BaseT to the same switch. The file server shares the storage over SMB (Windows file shares).
Something in the last update to Lightroom Classic broke this. It was fine in 5.x, 6.x, and Classic through 12.0.
Now, I can still open and edit files from the file server, but, if I try to synchronize a folder, Lightroom will crash (screen goes grey, and, eventually, a popup shows up saying that the app has become unresponsive). Checking in Task Manager shows lightroom.exe pegging a couple of threads and leaking memory. After about 30 minutes, the process had allocated over 11GB of memory.
Process monitor shows a lot of looping between reading the adobedesktopservice.xml, accessing the RTCommon.db, and calls to AdobeIPCBroker.
This is a synch step which, previous to 12.1, took a few seconds.
Sometimes it hangs before bringing up the synchronization page. Usually it hangs after bringing up the page, but without displaying any images. A couple of times it brought up a partial preview of images (10 or so).
Any ideas on a way to make this work again? I think it's a shared component that was updated by 12.1, because switching back to 12.0 did not revert the behavior.
I have an open case with Lightroom support, but they have suggested that I should not use network storage for image files, and should instead manually copy files to my laptop before importing them, and then copy them back to the network when I'm done editing them. That is not an acceptable solution for me.
Thanks,
Paul
