Has anyone seen a panic: 'page not free on exit' in the function dfalloc ? I'm running an old Compaq 386, with Xenix 386. I get this occasionally. I have 4 MB of memory. I'm not sure whether this is a kernel bug, or defective memory. It occurs about once or twice a day (on bad days). I've played around with 'big' programs - mallocing lots and lots of memory, and tried randomly accessing different pages in my address space. My thoughts were that if I had defective memory (say at the top end of my address space), the syptoms may be no different to a kernel bug handling virtual memory. I've tried running the DOS memory diagnostics and they passed (although I haven't thoroughly soaked the machine, overnight, say). Another problem I have is that after the panic, when I fsck the system, I have problems in my root filesystem, which never quite go away. Pass 5 gives me lots of unref'ed files even if I haven't created anything. (After the dfalloc panic, I reboot and sync the system just before I run my big memory test proggies). Anybody else had the same problems ? Thanks.
