MapGuide Server stop working

[Vladimir G. Kogut]

MapGuide Server suddenly stopped working when trying to invoke layers
from MapGuide Studio.
Found two related logs:

1) From system's .NET runtime:
"
EventType clr20r3, P1 studio.exe, P2 1.0.0.16802, P3 442a5bae, P4
autodesk.mapguide.studio.site, P5 1.0.0.16802, P6 442a5ada, P7 e1, P8
5f, P9 system.net.webexception, P10 NIL.
"

2) From Apache's error.log file:

"

Please, any ideas how to fix it, except reinstalling everything?

Thanks,
