Slow season so I'm going through our Qlik environment cleaning up minor log errors and warnings. Normally I can find great info here about what each means but this one eluded me. We have a bunch of warnings:

 Purged document entry remains non-isolated after X minutes

I assume this mean Qlik can't delete something that it doesn't need anymore? Or....something? Anyone point me in the direction of what this means generally?

Thanks
