What other device drivers, especially the IFS stuff, are you loading? What size cache are you defining for these?
The symptoms you describe all look & feel like the "out of memory" stuff I was seeing when testing the very large (>1G) JFS cache sizes here.
I usually let the IFS stuff as it is defined by ArcaOS installer. For older systems I also don't have big JFS cache. HPFS386 is remed out since long as it produces similar problems.
'mem -v' - my last tests on a pretty vanilla ArcaOS system I build up last week leads to 'out of memory' even when trying to open 4os2 or cmd windows. Sometimes afterwards it magically worked for one session but no more. -> very weird behavior with VIRTUALADDRESSLIMIT=3072. Reminds me on same experience a few years ago with another system.
So for me I can't get any system to work only near reliable with 3072. Wild guess, it may interfere with my 3840 x 2160 resolution. My observations lead me to guess there is a memory problem with the WPS or gradd or VMAN or ... with this high resolution too.
Administrator - this now runs very off topic. Maybe you wann split this thread. Thanks.
