When connecting to ArcSDE, the following error message occurs:
“Initialization of the dynamic link library WINNT\system32\COMCTL32.dll failed. The process is terminating abnormally."
On Windows NT, the ArcSDE service is started as a noninteractive desktop. The maximum amount of heap memory allocated
to noninteractive desktops is limited by a Windows NT initialization parameter called SharedSection.
The default value is 1024,3072,1024. The third argument--1024 kilobytes, or one megabyte--is the maximum amount of heap memory allocated to noninteractive desktops.
At this setting, an ArcSDE application server accepts approximately 132 connections. Each time a desktop spawns a process (in this case the ArcSDE service spawns a gsrvr process for each ArcSDE connection), it consumes some heap memory.
Increasing the maximum heap size of noninteractive desktops to two megabytes, for instance, allows the ArcSDE application service to spawn up to 270 connections.
The SharedSection value would be 1024,3072,2048 when the noninteractive heap size is set to two megabytes.
