rx4640 panic crashes: mblk is bad
We have been running an rx4640 Integrity Server as an HPVM host (HPUX B11.31) for two years with no problem. For the past week it has crashes several times. The crash dump pointing to NIC card, or vNICs shared by two clients.
I have five crash dumps, crash1 and crash5 give panic messages and stack-trace as follows:
hpvmdvr: AVIO VSD driver registered successfully, VSD version = 2:2:1
pmanLanFrameDataAvailable: given mblk is bad. mblk=e00000071a37a180, ptr=e00401000f21e936.
panic: pmanLanFrameDataAvailable: given mblk is bad.

End of Stack Trace
The other crash dumps simply says "bad news":
hpvmdvr: AVIO VSD driver registered successfully, VSD version = 2:2:1
Bad News: pr == 0x144000c0b10c003d
Bad News: Cannot use the Kernel Stack when interrupted on the ICS.
Bad News: Predicate set: 0x144000c0b10c003d.
I have one external NIC card, shared by two VMs
0/1/2/0 lan HP A6825-60101 PCI 1000Base-T Adapter
Since the trace has a line with hpvm,
hpvmntdvrrput+0x1e0,
It makes me think it might be software related to the HPVM, not really the physical NIC.
Any advice is appreciated.
Thanks

Re: rx4640 panic crashes: mblk is bad
Hi ,
mblocks are used by all the network stack.
a bad mblock just mean that there may have been an error before- double free for instance.
It never work with guess work,
you should contact hp support.

Re: rx4640 panic crashes: mblk is bad
Hi Kang,
This is a known issue with NFS version B.11.31.04 and is fixed in version B.11.31.06.
Suggest you to install the latest version from www.software.hp.com and search for ONCplus.
https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=ONCplus
Best Regards,
Prashanth

Re: rx4640 panic crashes: mblk is bad
As a fist guess you can indeed bet on ONC 11.31.04, and indeed it gives that type of result.
But it is not the only one.
Statistically if you have ONC 11.31.03 OR 11.31.04 it is the most frequent problem which lead to that type of panic but any double free of a mblock will give the same result.
but here it is only guess work.
