hmmm...  wonder if this is the denial of service due to SNMP SR:
8606-206689 - SNMP VolumeTable lookup ties up CPU.

I was able to identify this on my machine and found SNMP running in
glance while the 5-10 second hang is seen.

P82   SYS MANAGER.SYS            82 SNMP       C152  4.7%   0.1   0   0.0
CPU

workaround is to disable snmp:

snmpcontrol stop (each time after the network is started)

or to install patches:

SNMGDM1 for C.70.00 (beta test)
SNMGDM0 for C.65.00 (beta test)
SNMGDL9 for C.60.00 (general release)

I hope this helps.
