[mapguide-users] Mapagent error with blank image

[Rémy Gourrat]

Hi,

Under Oracle, Check the system view V$RESOURCE_LIMIT

And the lines MAX_UTILIZATION

I had a similar issue when limitations are effective.

If this is the case you can increase limitations, follow this link :

Hope it's help

Remy

Objet : Mapagent error with blank image

We have a production environment with:

MapGuide OS + Apache (2.6.08316)
Windows Server 2008 R2 Standard x64 - 8GB Ram - 8 Core
Fusion WebLayout
The MapDefinition has about 100 layers (all layers are linked to Oracle Spatial 11g with kingOra FDO)
About 100 user logon/day (mainly in working time from 8:00 AM to 5.00 PM)

Sometimes we experienced an error in the mapagent.fcgi call. The result  in the browser is a blank map image with a red x (instead the map).
There are no errors logged the Apache error log or in the Mapguide error log so we can’t find the problem that cause this error. The only think we found is that the problem occurs more often when the system is under intense usage.
Both Apache and Mapguide services is still running but all the call to the mapagent.fcgi fails (So it seems that this is the component that stops working).
The only solution we found to restore the functionality of the system is to restart both Apache and Mapguide services, because restarting only one doesn't resolve


Summarizing:
 Problem:
 fcgi error
 Result:
Blank map image in the browser
 Solution:
 Restart Apache and Mapguide server
 Question:
 How can we identify or log the cause of the problem?

 Best regards
