This is what CrashPlan support said:
"If there is a large file in use and CrashPlan is trying to upload it, it may cause a conflict. I believe that turning off the real-time file watcher should prevent this from happening."

Thanks for the link, that is very interesting, I also use CrashPlan for backups.

My LR catalog is on a drive with 670GB free space, just how much more space is needed?

It seems to me that a more likely explanation is a bug in some code, either the plugin, or LR, and that it could be caused by a temporary file access/in-use problem, or a 32 bit overflow problem?

How much space free, I quote from my first post:
"I have plenty of disk space free, 60GB / 250GB on drive C, 670GB of 5.4TB on drive D, 1.8TB of 5.4TB on drive E."
I.e. 60GB free on drive C, 670GB free on drive D, 1.8TB free on drive E.

If I remove the plugin, and work with LR, I never see that error.

Hi

Since I upgraded to the new v3 plugin, I frequently get errors that LR needs more disk space, and that I must free up 20MB.
I am not 100% sure, but I think this error comes from the plugin, as it normally happens wen I interact with the plugin, and it only started happening after I upgraded to v3.

If I just click the ok button a few times the error goes away.

I have plenty of disk space free, 60GB / 250GB on drive C, 670GB of 5.4TB on drive D, 1.8TB of 5.4TB on drive E.

Does the error come from the plugin?
How do I fix it?
