Hello Hiten,
Tuesday, April 16, 2002, 10:52:03 PM, you wrote:

I increased NMBCLUSTERS just after installing... System dropped to DDB
several times on Intel Pro1000T adapter so I enabled another netcard
and disable wx0 interface and now system works just fine... It is not NMBCLUSTERS problem...
It seems to me it is wx0 driver problem...
I said in bug report that system running Intel SR1200 server.... It
have 512Mb of ram (real memory = 536608768)and two procesors PIII (CPU: Pentium III/Pentium III
Xeon/Celeron (997.46-MHz 686-class CPU).
-- Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE>
Also It have 3 network interfaces:
-- fxp0: <Intel Pro 10/100B/100+ Ethernet> port 0x1480-0x14bf mem
-- 0xfe760000-0xfe77ffff,0xfe790000-0xfe790fff irq 7 at device 3.0 on pci0
-- fxp1: <Intel Pro 10/100B/100+ Ethernet> port 0x14c0-0x14ff mem
-- 0xfe720000-0xfe73ffff,0xfe750000-0xfe750fff irq 9 at device 4.0 on pci0
-- wx0: <Intel PRO/1000 T Gigabit Ethernet> mem
-- 0xfebd0000-0xfebdffff,0xfebe0000-0xfebfffff irq 2 at device 8.0 on pci1
Also there is IDE RAID massive ar0: 76345MB <ATA SPAN array>
[9732/255/63] that have device driver with unsupported dump routine so
I can't produce kernel memory dump for debugging... I used DDB to get
backtrace that I post in bug report...

I tried to play with tunables... But it doesn't help... System crashes
on sendto syscall almost every hour :( when load is high...
