I have added ClearAnchors() to every line of SetAnchors() in LibAddonMenu-1.0, then replace all the exist library that other AddOns are using, still get the error. I'm stuck here once again, and start to feel that it is the limit of the game client rather than the code...

EDIT: I have managed to recreated the error by install enough AddOns that are using LibAddonMenu-1.0 with Reticle Settings disable. So, I can now confirm that Reticle Settings itself is not causing the error (but kinda add the load into it due to many customization options I put in, and make this problem to be found quicker before someone else install enough AddOns to found that error anyway). Bug report has been posted at LibAddonMenu's page.

I just look inside LibAddonMenu-1.0 code, and apparently there are lots of SetAnchor() but not ClearAnchors(). I might try to fix them up and see if that would help with the error. We might have now found the final boss here to get rid of this problem once and for all.

That's a good idea of putting version number by the AddOn's name. I'll start doing that as well for the next update.

I have no idea what within LibAddonMenu library that cause the overloaded error. It could even be the game itself can't handle the load, I really don't know. Further testing is requires by coding all the options in settings panel from scratch without the use of code library and see if large amount of options would still result in error.

I actually haven't done anything in version 1.5.2 except apply this patch. So not quite sure what happened there, apart from that you might have disable some AddOns out from the list to left some room for other AddOns to process.

Well, at least I'm going to sleep better tonight.

I've managed to find an AddOn that can help me replicated the error, and now I believe I have found what is causing "Too many anchors processed".

It's something to do with LibAddonMenu-1.0 as I fear. The problem happen when you install lots of AddOns that are using the library and has many settings. All of them combine kinda reach the limit of what the game or the library can handle, then it give out the infamous error.

Reticle Settings alone with other AddOns that does not put much options in their settings panel, no problem there. But when you added them all together, it continue to pile up and cause the error when it hit it peak. You can remedy this by remove one or two AddOns that also using LibAddonMenu-1.0 to help reduce down the work load, and the error will be gone.

That's why it seem to be ramdom of when the error appear as you enable the AddOns from top to bottom, or from the bottom up to the top. If you do the same AddOns enable sequence, you will have the same result of when the error will appear.

At this point, I have no idea how to fixed this issue except cut down all the new features I have added to the AddOn. It might worth checking with LibAddonMenu's author and see what's up with that, and what is maximum AddOn's setting you can have.

Well, one step closer toward the goal.

EDIT:
Wykkyd Framework
Simple Combat Alerts
Reticle Settings
Azurah
Thurisaz Guild Info
Range Reticle

Those are the AddOns that are heavy in having lots of options in their settings panel, and using LibAddonMenu's library heavily.

EDIT2:
Simple answer -- The more AddOns you installed, the more likely you will encounter "Too many anchors processed".

It is the same as before, but just fixed an error when you do range target. All the too many anchors processed still there to play around and cuddle with.

EDIT: Here is my thought of what I could do. I could do a reverse engineer of my AddOn by remove new features I have added since v1.4.8 one by one and see which one trigger the error. Will need sometime to do it so please bear with me here.

Yes, it's how I have managed to clear anchors before set them. Strange enough that those code still existed in version 1.4.8 without clearing them and show no sign of error.
