<p class="MsoNormal"><span lang="EN-US">So I have this error as well. I mostly see it when a connection times out. Like you mapserver shows no errors but apache has the script ended before headers error. Do you have fcgi enabled? If I disable fcgi I don't get
that error, so It could be related to connection a user has to mapserver. Maybe FcgidMaxRequestsPerProcess, FcgidMinProcessesPerClass, FcgidMaxProcessesPerClass need to be tweaked?<u></u><u></u></span></p>

<p class="MsoNormal"><span lang="EN-US">You use &layers=default and I suppose that it means all the layers from your mapfile together. In that case I would try to catch the failing layer by adding layers
one by one and in groups (first &layers=layer1, then &layers=layer2, then &layers=layer1,layer2).
<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"> <u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">Hopefully that way you can find the failing layer, and then because you know the BBOX you may find the nasty geometry from the database. Without your data and
mapfile it is rather useless to make very much guesswork, but a small change in bbox may select/not select a bad geometry, of change of bbox may change scale so much that source data come from a different table if you have a scale dependent layer group in
the mapfile etc.<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"> <u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">If the issue is due to bad geometry and you use PostGIS you may find it with ST_IsValid and ST_IsValidReason, and correct with ST_MakeValid.<u></u><u></u></span></p>
