CX_OBJECT_MANAGER::FreeVirtualMemory ( from Dll version: 4.5.2.166275)

Description:

In a transaction ObjectStore allocates help objects for the reallocation of addresses, which disappear again at the end of the transaction.
When processing a large number of objects in a long transaction, we reach sizes of 10 × 106,¹⁰⁰ × 106 auxiliary objects and often come to a halt due to
out of virtual memory exception.
FreeVirtualMemory starts a new ObjectStore transaction if (and only if) the allocated memory exceeds the maximum value passed as parameter.

1. caution: in a writing transaction you lose control over when to write back to the database.
2. use only if the basic developers have clarified that no memory leak in the ClassiX® system is the cause of the out of virtual memory exception.

Code example:

Function call: Call(FreeVirtualMemory)
