Hi everyone and John, I just got a panic inside the VM subsystem and I was dropped into DDB. I had switched to the console because the following messages started to appear on my console: May 28 19:10:39 keltia /kernel: vm_pageout_scan: page not inactive? May 28 19:11:07 keltia last message repeated 4 times May 28 19:12:55 keltia last message repeated 2 times May 28 19:19:06 keltia last message repeated 4 times May 28 19:23:00 keltia /kernel: vm_pageout_scan: page not inactive? May 28 19:23:08 keltia last message repeated 459 times May 28 19:23:08 keltia /kernel: not inactive? May 28 19:23:08 keltia /kernel: vm_pageout_scan: page not inactive? It was getting News from my laptop with nntpsend during that time. Every process I launched caused more messages to appear on the console. Soon after their appearance, the system panic'ed: kernel 12 trap, code = 0 stopped at _vm_page_alloc+0x1d0 movb 0x24(%ebx),%cl db> trace _vm_page_alloc (f0ec7100,1,0,efbfffbc) at _vm_page_alloc+0x1d0 _vm_fault (f0ecbe00,81de000,1,0,efbfffbc) at _vm_fault+0x595 _trap_pfault (efbfffbc,1,81dd060,1cf0f4,33b0a4) at _trap_pfault+0xb1 _trap (27,27,33b0a4,1cf0f4,efbfce34) at _trap+0x15b calltrap() at calltrap+0x15 trap 12, eip = 081d0982, ebp = efbfce34 %ebx = 0 On a side note, I'm getting various sig6/10/11 from some processes (emacs generally) since the last VM changes. I'm not up-to-date since my primary mail machine is down but I've got sources from the following date: cvs-cur.2043 1996/05/26 08:00:01 486DX4/100, 32 MB, 2x SCSI controllers (BT-747S & AHA-1740A). Boot messages available.

It generally hang during the first launch from Elm (it just did it as I started writing this mail !) and hitting 'e' launch it again without problem. As my kernel is not compiled with "-g", I don't have a better trace... As soon as my mail machine goes up again, I will upgrade so I apologize if it is already fixed. -- Ollivier ROBERT -=- The daemon is FREE! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 2.2-CURRENT #4: Sun May 26 14:34:02 MET DST 1996
