Hello!
I've found strange things with 2.3.7 compiled with gcc 2.7.2.3 It's IP system/UP kernel Linux angband 2.3.7 #16 Mon Jun 21 19:53:45 MSD 1999 i586 unknown Just after boot: angband:~$ free total used free shared buffers cached Mem: 30664 29596 1068 22896 80020 20316 -/+ buffers/cache: 4123564 101404 Swap: 102780 124 102656
Strangely enough I have 32M RAM there and 80M of them in buffers??? And I can Lockup this box completely with this little program: #include <stdio.h> #include <stdlib.h>
void main(int argc, char *argv[]) { int i,t=0; char *tt;
while(1) { tt=malloc(1024*1024); for (i=0;i<1024*1024;i++) { tt[i]=1; } t++; printf("Allocated %d M\n",t); } }
It's output: angband:~/danger$ ./a.out Allocated 1 M Allocated 2 M Allocated 3 M Allocated 4 M Allocated 5 M Allocated 6 M Allocated 7 M Allocated 8 M Allocated 9 M Allocated 10 M Allocated 11 M Allocated 12 M Allocated 13 M Allocated 14 M Allocated 15 M Allocated 16 M Allocated 17 M
And now box answers only to Alt-SysRq etc. First time I tried this after few console switces I got complete lockup: No switches, no cursor, no Alt-sysRq, blank screen.
No oopses were found. But FS is corrupted, e.g. If I write some file, and then run this proggie, I have the file in place, but contend is random data. (Well not very random, once I got old dependency file from kernel) Actual data sometimes found by fsck and attached to /lost+found, and sometimes - not found.
