[mapserver-users] Slow Response or Timeout for Mapserver

[Berger, Cora]

Hello Jeff,
thanks for the advice.
I checked the access logs and found out that our MaClient - Application (all the requests work fine here) makes POST-Request.
E.g. 

10.213.35.10 - - [30/Jun/2016:11:56:11 +0200] "GET /cgi-bin/test5?REQUEST=GetCapabilities&SERVICE=WMS HTTP/1.1" 200 10997 "-" "Java/1.6.0_30"
10.213.35.10 - - [30/Jun/2016:11:58:01 +0200] "POST /cgi-bin/test5 HTTP/1.1" 200 321529 "-" "Java/1.6.0_30"

QGIS and our Open Layer applications use GET-Requests for the map-Request. Sometimes those requests don't seem to reach the server, because they are not logged if the request runs on a timeout or sth. 
We get a Mapimage if Firebug is on. A working request from the access-log looks like this:

10.213.31.120 - - [30/Jun/2016:07:11:40 +0200] "GET /cgi-bin/test5?REQUEST=GetCapabilities&SERVICE=WMS HTTP/1.0" 200 10997 "-" "-"
10.213.31.120 - - [30/Jun/2016:07:12:33 +0200] "GET /cgi-bin/test5?LAYERS=&FORMAT=image%2Fpng&TRANSPARENT=TRUE&STYLES=&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG%3A25832&BBOX=-181189.87723015,5458184.3609017,992882.87723015,5939737.6390983&WIDTH=1920&HEIGHT=787 HTTP/1.0" 200 354 "http://vbrk21nt15.bezreg-koeln.nrw.de/tim-online2-chg/timobile.html" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0"

We have Mapserver 7.0 and Mapserver 6.3 running on Windows-machines and never has any comparable problems..

Hello,

I would check your Apache access logs for the full requests, and compare 
them for the different clients (OpenLayers, QGIS, etc.), you might even 
paste 2 of these full GetMap urls here for the mailing list to compare 
the parameters - maybe one client is using something different causing 
your issue (?)

I had been facing a lot of truncated GetCapabilities requests in the 
MapServer 6 series, but have not seen any issues with MapServer 7. 
(there were lots of tickets for that old issue, but here is one example: 
https://github.com/mapserver/mapserver/issues/4505)
