Hello my name is Darren, I used to do troubling shooting of hardware equipment for a Point of Sale Company for over 22 years for a living, have an A+ certification many years ago. Product = Quest2 128GB bought in 7/29/2022, Issue = memory error - "Not enough memory to run xxx" , Occurrence Random = About 10-55min. Versionv81.xx For about 2 weeks I also have the issue of "Not enough memory to run xxx", for instance running "Dungeons of Eternity". it happens about 10min-55min. in the game but most all the time when everyone is linked to go back to the starting area in the "D. O. E. " game, after the fight, where everyone makes it back, except me, sometimes, more often while someone is talking the APP crashes and I recover back to the Meta Home screen. I've did some research on this using Gemini, it said that the heatsink fan may not be working so bought tools to take it apart checking to see if the fan was clogged or not turning , it was still working, no clogs, so not that as the issue. I've since backed up my apps on the cloud. and 2 different times Reset the Quest2 to Default then only loaded the game "Dungeons of Eternity" & VRChat App. All other Apps are self installing by Meta including Facebook, Instagram, and a few other Meta apps. It sounds like only Quest2's have this issue with crashing I was going to purchase a Quest3, until I found another person crashing in the middle of playing this game. My friend said "it's happening more now" and not just Quest2' s but also on Quest 3's as well so it seems IMO that this is a memory leak issue that needs to be corrected with ver. 81.xx since I never had these issues on previous Quest updates. Thanks for reading this.
