King.Oracle 0.7.3 (0.7.4) Memory Leak with MGOS 2.0 (2.0.1, 2.0.2)

[fisher]

I have been faced with a problem of memory leak by working with MGOS 2.0.2 (2.0.1, 2.0) and FDO-Provider King. Oracle 0.7.4 (0.7.3). In our base we have only 10000 objects. The problem appears by the typical work with the map (distance, approach). I have sampled the change of used memory after each operation:

		RAM	VM	CPU 
Time
Start Service	40	36	0.01
Load Preview	64	58	0.011
Zoom In		65	59	0.014
Zoom Out	68	62	0.020
Zoom In		69	63	0.024
Zoom Out	72	66	0.030
Zoom In		73	67	0.024
Zoom Out	76	70	0.040
Zoom In		77	71	0.043
Zoom Out	81	76	0.049
...		...	...	...
		1570	1480

By the reaching of the volume of used memory up to 1570Mb the service doesn’t respond to any request. After that the process mgserver.exe is crashed.

Data from the file Error.log:
