I get a lot of insteon link errors in my insteon
explorer. I don't go in there very often, maybe once a
month??? Well, when I do, I almost always have [ID NOT
FOUND] and [INSTEON TYPE NOT FOUND] errors on many of my
devices. Is this indicative of some error in my system,
or does it happen to everyone. It's kind of a pain going
through each and every device deleting all of these
errors. I have about 50 devices, and yesterday I must
have cleared over 100 of these errors. For the most part,
everything works fine, and I wouldn't have known about
the errors if I didn't have to go in to reactivate my
Christmas lamplincs and appliancelincs. But it is still
annoying and it makes me wonder if I have some other
issue that I should be looking for.

Here's a copy of the raw log as I was deleting many of
these. There are some timeouts in there. Could that be the
problem?

Skip,
The ID NOT FOUND errors are usually the result of garbled Insteon communications (which is supposed to not happen with Insteon).
If you have "Link Scan" checked, PowerHome automatically scan a devices links when it thinks a change has occurred (either a real change or bad comms again). Insteon comms can become garbled so that as a link is scanned, the address may not match what was previously scanned (PowerHome has no way of knowing if the comm got scrambled) so a new entry is created in the Links table. If this address is for a device that does not currently exist in the Devices table (usually the case if the comm was scrambled) then you'll get the ID NOT FOUND.
Keep in mind it could also be a legitimate new device but if you haven't made any changes to your Insteon network recently then its most likely bad comms.
Best way to combat this is to uncheck "Link Scan" so PowerHome won't automatically scan links and only check this when you've made a change to your system. The other thing you can do is try to improve your Insteon comms (use the Reports tab in Insteon Explorer). This will help but not cure the problem as even with perfect comms, Insteon comms will still occasionally scramble. Scrambled comms should be greatly minimized with I2CS devices.
Dave.

I have unchecked Link Scan as you suggested. But I am
wondering, does link scanning and poll interval have
anything in common? If link scanning is enabled, is PH
always scanning for links? Or only when poll interval > 0?
Thanks for the help, Dave!

Poll interval controls all background operations. When the poll interval is expired, PH goes through a long series of checks to determine what it should do during this poll. Thinks like checking if a devices links should be scanned, should a link be created, etc. Last on the list is just a standard status scan.
So to answer the question, yes the poll interval must be > 0 to have a link scan done. PH won't do a link scan though unless its been requested (like Scan DB checked) or its detected a difference in the database revision through a status check.
Dave.
