We had this problem even on the beefiest of servers, dual proc E5 64Gb of ram, LSI raid with 8 drives and 1gig write cache. We still occasionally have the issue and have invested many man hours trying to fix. With that said, it seems like the software itself is the issue.
UBNT needs to quit developing in Java. It sucks, and will always suck. MongoDB was a poor choice as well, or at least how they implemented things. It has far too large of a dataset, so you can't back the thing up. They need to quit storing things that way. My advice to them is to create a separate database for every camera, and have a database for the main NVR operations if they want to continue down that road. That way when one piece of the puzzle doesn't fit, the whole thing doesn't come crashing down. I have Datasets that are 250GB large keeping track of 25TB of footage. You can't reasonably back that up or scan it for errors without waiting several days, so upgrades tend to be all or nothing without rollbacks. Version 3.4 works better, still not great. And on top of that, a new fix they posted for enhancing performance seems to have completely corrupted one of our databases we tried it on for one of our larger installs. Now we may have to wipe several months of footage that is critical. They have since removed the post without a sorry or an explanation... At the end of the day, if it's mission critical, pay for Milestone. Regards Chris Ruschmann -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Shawn C.

Half the time i have to reset the appliance to even gain access. I am getting slot of "nvr is not reachable errors" and can barley view archives. Hard drives seem fine. Anyone else experiencing this?
