It's the usual thing: it's impossible to say anything about the problem if you do not add the error logs of PHP/Javascript. One quick guess is that the path to the produced map image file could be pointing to the wrong server (depending if you have sticky sessions or not). At work we are using a piece of p.mapper with sessions in PG and Apache proxy/balancer. The tmp dir for the produced images is on an NFS network mount, so it will be found by both servers. If this is the problem in your case you can also just use NFS on one server mounting the tmp of the other (this way not requiring a network storage solution). armin ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
