[mapguide-internals] FW: [mapguide-users] MapGuide runs out of FDO connections under Fusion MGOS 2.1 Beta

The interim build still has old fusion code; have you tried the latest commits against this ticket?  There were a couple more ->close statements that weren't quite right.


Also, are you using connection pooling?  I've never turned this on for SDF.  If so, can you try without and see if it makes a difference?

The best way to get this fixed is to provide a simple-as-possible test case (preferably attached to a Trac ticket) that would allow a developer to install and duplicate the problem within a few minutes.

I still think I remember seeing something where the old mechanism for creating selections caused leaks in .Net where the new method (based on map name) did not, but can't for the life of me find any reference to this.

I just tested with the interim build and the problem of SDF FDO connections
not being released still occurs.  With a pool size of 200, the MapGuide
server hangs after 100 setSelections and must be restarted.  (Each
setSelection ties up one connection during execution of SaveSelection.php
and another during execution of GetSelectionProperties.php)  This is 100
total setSelections since startup, not 100 per user.  It doesn't take many
users or much activity to bring down the server.

This is a severe problem that prevents Fusion applications from being
deployed.  Is there an 'official' way I should be reporting it?
