Solution

OutOfMemoryException in Agent/PME usually isn't about available memory but it is more memory fragmentation problem, The process is asking for continuous block of memory, but available memory is fragmented to small chunks. It happens usually on Server systems with slightly different .NET memory engagement than Workstations.

This is a system level issue
