If the name of an Organizational Unit (or multiple names together) in AD are longer than 255 characters, the following error occurs during the AD import:
"Failed to generate import data. Insufficient memory to continue the execution of the program. [System.OutOfMemoryException @ mscorlib]""
Steps to repro:
1. Create an OU in ad or multiple that together are longer than 255 characters
2. Create at least one computer in the OU
3. Create an import rule or modify an existing one to import the newly created OU and Computer
4. wait for the error
Failed to generate import data. Insufficient memory to continue the execution of the program.[System.OutOfMemoryException @ mscorlib]
The fault was in resource key parsing for long paths, which leads to endless XML writing.
