I've got four vhosts using different txt RewriteMaps. All of them contain an entry with key '/' besides others which are unique. The maps are generated automatically. If the maps are of the same age (generation is very fast) the entries for '/' behave as configured round-robin. The effect disappears as soon as I slow down the map generation to get different timestamps for the map files. Configfiles can be supplied if they are considered relevant.
Yep, your config would be of interest. Thanks.
(I've received the config via mail) Sorry for the long delay. However, the problem is, that you're using the same name for the maps, which confuses the rewritemap cache. The problem is fixed now in 2.1 and I'm going to propose it for backport into 2.0 and 1.3 branches. I've uploaded a patch for 1.3 here: <http://www.apache.org/~nd/mod_rewrite-confusion-1.3.patch>. Thanks for the report and thanks for using Apache.
The fix will be in 1.3.32.
