I compiled mod_tile again with svn-r28921 containing today's change from apmon which writes the actual load into error.log. The result is strange:

	[info] [client xx.xx.xx.xx] Load (1202590843) larger max_load_missing (500000). Return HTTP_NOT_FOUND., referer: http://xxxx.xxxx.xx/

Quite some high load, isn't it? I hadn't time yet to dig deeper but will do that the coming days. If in the meantime someone has an idea: feel free to share :-)

Greetings, Stefan
