Re: AMI MegaRAID datapoint... or is it NFS

[Matthew Dillon]

:Another thing I've found with the MegaRAID (or maybe this is an nfs
:thing?) is that large scale (100Mb, full duplex) hits on the NFS
:server tend to lock up the nfs server (which has the megaraid in it).
:Typically, this includes not being able to access the non-raid root
:var and usr partitions.

:Any ideas?  I can reproduce the problem, but it doesn't cause a panic.

You need to figure out what the processes are locked up in.  If 'ps axl'
doesn't work then you need to ctl-alt-esc into DDB (assuming the kernel
is configured for DDB) and do a 'ps' there.  

It should be possible to narrow the problem down from that output.
