What i think is my issue (still not sure) is that when i check the system stats with webman it tells me there is only 2,000kb of free memory when i am on XMB, i think my machine is running out of available memory and freezing.
When i check the same stats in MultiMan, it tells me the system has 60,000kb of free memory.
You can will find different amounts in these. Each uses a different allocation of memory set aside for various tasks.
WebMAN is showing you the available '
SystemOS' memory available, basically the memory (RAM) set aside to operate the system, XMB, firmware, boot files, plugins etc, as webMAN is written into the XML of the XMB and uses sprx's loaded into the firmware flash memory to operate. If you have a low amount here you might want to check your '
boot.txt & prx.txt' to see how many plugins you have running in the background.
MultiMAN on the other hand shows you the memory available that is set aside for the '
GameOS' as it uses this to operate. Basically the memory for running your games and apps stored on your HDD. Also for using you mods and things for games.
If you're system memory runs low your console will shut down and reboot into '
Safe Mode' and you will get a message say '
System cannot run correctly'.
If your memory for running games runs low or out it will crash the game and/or Console. And sometimes it will give a similar message '
Game cannot run correctly' and exit to XMB or reboot the console. Normally if your running high demand games with high demand mods. Usually I have found it will just crash.
My systems sits at 50'c when playing as i have the fans set running at 42%.
That is a bit high of a fan speed to keep it that low, 25% normally keeps mine below 60°C running high demand games such as Call of Duty. maybe you have a cooling issue? Have you tried replacing the Thermal Paste and cleaning out the Heat Sink and Air Flow ports of dust?
Minecraft isn't exactly a high demand game when it comes to taxing the RAM so I can't see that crash your console unless of course you're modding the hell out of it. So inturn wouldn't put to much of a stress on the CPU & RSX and send the temps high.
Have you also tried reinstalling your Firmware to see if that resolves your crashing issue?
Also frequently crashes can be as a result of a HDD about to fail, high fragmentation of the HDD especially if the HDD is used alot and/or is old.
