#3748 new defect

intermittent WMS Projection library error

Reported by: basic999 Owned by: mapserverbugs
Priority: low Milestone:
Component: WMS Server Version: 5.4
Severity: normal Keywords:
Cc: aboudreault


WMS server with "wms_srs" "EPSG:3857 EPSG:4326" gets projection error. EPSG:3857 is used by OpenLayers page and EPSG:4326 is used by QGIS. As long as WMS request is only from one of these sources they either work correctly. If QGIS makes successful request for layer in projection 4326, then the OpenLayers page request will get random

msProcessProjection(): Projection library error errors.

Restarting Apache web server will fix problem for first use of either of these, but the other will then fail.

Um... that won't be an easy one to reproduce. You seem to be using MS 5.4. Can you see if this still happens with MapServer 6.0.0-beta?

Also, what is your OS, and is your Apache using MPM prefork or worker?

comment:2 by basic999, 13 years ago

We are running a university supported version of 64-bit Red Hat 5 server. Compiled in modules:

core.c prefork.c http_core.c mod_so.c

If you want you can downgrade this to a low business priority, as we are just using it to run some OpenLayers pages and it is working for that.

I'd still like to see this fixed, but in the context of other priorities I agree that we can consider this one as lower priority, especially since it is probably specifically related to the use of PHP as a wrapper for OGC services and I'm not aware of reports of similar issues with FastGIS for instance.

errr.. in the comment above I meant "... not aware of similar issues with FastCGI..." of course. Not sure where that FastGIS came from!
