Hi ...

  Over the past little while, two of my servers have suddenly started to hang
... servers that up until this started, have been reasonably rock solid ...
they are generally within a day of each other for source code, and the hardware
on both are pretty much identical (HP Proliant DL360 Servers) ...

  I have serial console configured on both so that I can do CR ~ ^b to get to
DDB ... except, when it hangs, all I get is:

"KDB: enter: Break sequence on console"

  And it hangs there, no prompt.

  I setup a simple script (see attached) to run every 5 minutes that gathers
various pieces of info that I think are pertinent, but most likely don't cover
everything ...

  Whenever this happens, on either machine, vmstat show data *like* (notice the 
high procs -> w values?):

 procs      memory      page                    disks     faults         cpu
 r b w     avm    fre   flt  re  pi  po    fr  sr da0 pa0   in   sy   cs us sy

  Where procs -> w just seems to keep rising ... note that the output for
vmstat *5 minutes before* shows:

  I have one QEMU VPS running on this box, with kqemu running the latest kernel
module ... but the other machine experiencing the same issue is only running
FreeBSD jails ...

  Both servers are running SCHED_4BSD, if that matters any ... ?

  I'm at a loss as to what to look at / for next ... pointers would be greatly
appreciated ...

  I have the various output files that the script generates available if anyone 
thinks they would be useful ...

thank you ...

Dear friends,

I'm having some problems in a server HP DL180 G5  (part-number 456831-201)
with a HP Autoloader 1/8 Ultrium 920 G2 (part-number AH165A).

In this server is working FreeBSD 7.1-STABLE ( the last version ).

It knows the SCSI controller on "mpt0: <LSILogic 1030 Ultra4 Adapter> port
0xe000-0xe0ff mem 0xfcee0000-0xfcefffff,0xfcec0000-0xfcedffff irq 16 at
device 8.0 on pci7".

But the problem is that when I turn on the server ( HP DL 180 G5 ) with the
HP Autoloader connected it shows the following error message and freeze (
the server stops responding =( ).

mpt0: EvtLogData: IOCLogInfo: 0x110a0000
mpt0:   EvtLogData: Event Data:  05020014
mpt0: mpt_cam_event: 0x1
mpt0: EvtLogData: IOCLogInfo: 0x110a0000
mpt0:   EvtLogData: Event Data:  05020014
mpt0: mpt_cam_event: 0x1
mpt0: EvtLogData: IOCLogInfo: 0x110a0000
mpt0:   EvtLogData: Event Data:  05020014
mpt0: mpt_cam_event: 0x1
mpt0: EvtLogData: IOCLogInfo: 0x110a0000
mpt0:   EvtLogData: Event Data:  05020014
mpt0: mpt_cam_event: 0x1
mpt0: EvtLogData: IOCLogInfo: 0x110a0000
mpt0:   EvtLogData: Event Data:  05020014

While the server is not rebooted the messages do not stop showing. =Z

The SCSI controller is a SC11Xe, anyone could help me try to fix this issue?

Any idea is welcome ..

Thanks in Advance..
Leandro
