Hi all,

The Feb 20th patch does not aid the problem at all. I have randomly appearing 
dots and polylines too and a quick bit of debugging showed that I have nothing 
in the secondary nodes data at all, so the patch does not have any effect.

Furthermore, I think I have discovered the problem - the geocode requests are 
too quick and are hitting the Google Maps API limit (which is some number of 
requests every 1.7 seconds or something stupid).

I changed the geocoder.getLatLng call into a geocoder.getLocations to get the 
request status - all the points that are randomly failing are returning the 620 
error code - G_GEO_TOO_MANY_QUERIES.

I don't understand, however, how there are too many queries as the DeferredLock 
is acquired before the getLatLng call and then only released in the callback 
meaning the request should be done and it is only possible for one at a time to 
occur at once - is this correct, or have I misunderstood the DeferredLock 
semantics?

Maybe this information will help one of the developers fix the problem, as the 
Google Maps portlet is most useful and quite important to the large client to 
whom I've just rolled out Zenoss.

Regards,
Johan.
