I have a problem, when I use spilt screen online mode. After a few games, I got a disconnect, and an "out
of memory 29" error message. I tried all the methods, what I have found on the net. I turned my ps off, unplugged the charger and waited 3-5 minutes to reset cache memory. I deleted a lot of saved data, and installed data from my HDD too. Although these things expanded the time period of the bug from every game to every 4th game, it still remained. By the way, I don't use share play. Furthermore, ps4 has an auto recording feature, which uses an other chip and memory to capture gameplay I guess, so it can't be the source of the issue.
All I ask is that, someone of the kind supporting staff, please help me to overcome this bug. I use this mode very often, and it's really annoying to get that error in the middle of every 3th - 4th match.
Two years later, I can confirm, that this issue has been fixed.
