[mrtg] Ongoing problem

I know I've posted this before, but I am going crazy...
Regardless of the PC I run MRTG on I have sporadic problems trying to graph
a series of Dell PowerConnect switches. Things will hum along nicely for
days / weeks and suddenly I'll start getting the following error...
no response received
SNMPv1_Session (remote host: "18.104.22.168" [22.214.171.124].161)
request ID: -747181493
PDU bufsize: 8000 bytes
SNMPGET Problem for ifInOctets.1 ifOutOctets.1 sysUptime sysName on
public at 126.96.36.199:
WARNING: skipping because at least the query for ifInOctets.1 on
188.8.131.52 did not succeed
Stopping MRTG and restarting it several times in a row sometimes
fixes the problem, other times I have to wait a day or so and then it will
work, but obviously having big gaps in my graphs isn't very useful.
Is it possible the switches are just getting overloaded and
can't respond to MRTG in time? Is there a way to increase the timeout
threshold for MRTG so it will wait a bit longer or retry the SNMP get? I
see the timeout and retries on the error, how do I bump these up? Or am I
way off base here.
