trunk, net-snmp-svn-main_20070619_0311.tar

agent, sorry about being a bit ambiguous.

It actually changes now that I did some hammering with snmpget, 
sometimes the agent hangs on hrStorageUsed.38 (or actually anything over 
38). Target seems to move a bit...

Pretty messy, but that's what I get after jumpstart installation of 
sol10. I've tried the skipNFS switch in the config, makes a difference 
in the output but it still hangs.

The .38 has funny path though, shouldn't be /vol at all but point to a 
real mounpoint on the fs...

hmm how did strace work on solaris again?

here's something from truss in the meantime:

time()                                          = 1182392413
pipe()                                          = 11 [12]
pipe()                                          = 13 [14]
schedctl()                                      = 0xFEC70000
fork1()                                         = 19387
lwp_sigmask(SIG_SETMASK, 0x00000000, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
close(11)                                       = 0
close(14)                                       = 0
close(12)                                       = 0
pollsys(0xFFBF4D60, 1, 0xFFBF4E38, 0x00000000) (sleeping...)

just before it hangs, seems to go back to the sleep cycle normally
