<div dir="ltr">Ludovico,<div class="gmail_quote"><div>I had a java mapscript connection timeout problem too. Making sure that every table with feature information in PostGIS had a corresponding record in the "geometry_columns" table and then doing a Vacuum/analyze/reindex on the database, fixed my problem. If you haven't done this already then maybe you can try this too. Just a suggestion.<br>

Are you sharing any mapscript object as an Action attribute? If yes<br>
that's probably the culprit, otherwis it seems pretty strange...<br>
Does the crash occur only when more than user is accessing the map or<br>
even when there is only one user?<br>
<br>
Also ms4w 2.2.3 seems prett old, why don't you upgrade to the latest?<br>
