Machine: Dual Xeon 3.6 Dell Poweredge 2850 8 gigs of ram 16 gigs of swap amr raid The machine will reliably crash under load within an hour or so. "under load" involves large network transfers being processed by cpu and memory intensive processes. i cant get a crash dump (when it starts dumping, it will stop part way thru displaying memory increments.) I have gotten it to spit out a trace from KDB, which i've copied out below. (i had to do it from a screenshot/by hand- i checked it twice, but if things dont make sence, there may be a typo) kernel config included below the trace. We've tried turning off hyperthreading. The problem persists. We've tried turning off PAE (which brings us from 8 gigs to 3). The problem goes away. This is obviously not the optimal solution. --- kdb_enter(c05a1e33) at kdb_enter+0x2b panic(c05a0a51,fffffffe,c05a0a3b,cb65ed80,fffffffe) at panic+0x127 lockmgr(cbadb7e4,6,cbadb738,0,f1b93a0c) at lockmgr+0x421 vop_stdunlock(f1b93a3c,f1b93a18,c038320f,f1b93a3c,f1b93a59) at vop_stdunlock+0x1f vop_defaultop(f1b93a3c,f1b93a58,c038379c,f1b93a3c,1000) at vop_defaultop+0x13 spec_vnoperate(f1b93a3c,1000,7f010000,cba4e100,f1b93aa4) at spec_vnoperate+0x13 spec_write(f1b93a84,f1b93ad0,c04fce99,f1b93a84,cb65ed80) at spec_write +0x64 spec_vnoperate(f1b93a84) at spec_vnoperate+0x13 vnode_pager_generic_putpages(cbadb738,f1b93be0,1000,0,f1b93b60) at vnode_pager_generic_putpages+0x221 vop_stdputpages (f1b93b18,f1b93b18,f1b93b04,c038320f,f1b93b18,f1b93b44) at vop_stdputpages+0x1a vop_defaultop(f1b93b18,f1b93b44,c04fcc36,f1b93b18,1000) at vop_defaultop+0x13 spec_vnoperate(f1b93b18) at spec_vnoperate+0x13 vnode_pager_putpages(cbb53ad4,f1b93be0,1,0,f1b93b60) at vnode_pager_putpages+0xba vm_pageout_flush(f1b93be0,1,0,cbd7a600,f1b93bb8) at vm_pageout_flush +0xcb vm_pageout_clean(c4254e4c) at vm_pageout_clean+0x2a1 vm_pageout_scan(0) at vm_pageout_scan+0x706 vm_pageout(0,f1b93d38) at vm_pageout+0x312 fork_exit(c04f5e1c,0,f1b93d38) at fork_exit+0x75 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip=0, esp = 0xf1b93d6c, ebp = 0 --- kernel config: include GENERIC ident PAE-GENERIC options KDB_TRACE options KDB options DDB makeoptions DEBUG=-g options SMP options COMPAT_LINUX device acpi makeoptions NO_MODULES=yes nodevice ahb nodevice amd nodevice sym nodevice trm nodevice adv nodevice adw nodevice aha nodevice aic nodevice bt nodevice ncv nodevice nsp nodevice stg nodevice asr nodevice dpt nodevice iir nodevice mly nodevice ida nodevice mlx nodevice pst nodevice agp nodevice de nodevice txp nodevice vx nodevice dc nodevice pcn nodevice rl nodevice sf nodevice sis nodevice ste nodevice tl nodevice tx nodevice vr nodevice wb nodevice cs nodevice ed nodevice ex nodevice ep nodevice fe nodevice ie nodevice lnc nodevice sn nodevice xe nodevice wlan nodevice an nodevice awi nodevice wi nodevice uhci nodevice ohci nodevice ehci nodevice usb nodevice ugen nodevice uhid nodevice ukbd nodevice ulpt nodevice umass nodevice ums nodevice urio nodevice uscanner nodevice aue nodevice axe nodevice cdce nodevice cue nodevice kue nodevice rue
