We are in a large project utilizing C4R under Revit 2017.2.4
On this project we are having consistent issues with BIM 360 Glue process on all machines working this project.
I thought I would try tweaking Virual Memory on one of the machines to see if this helps. But I am not certain what settings to use. I thought I try 4092 GB as this page suggests.
These machines have 32 GB of Ram with 280 GB Free space on C drive.
Other machines having the same issues have 2 TB SSD Drives. All of these machines are hi end machines.
What is the recommended settings for Initial and Maximum ?
... could this be the ticket to fix this issue?

HELP!
UPDATE:
I tried 4092 GB MB as this page suggests.
This makes 36 GB of VM (32 GB + 4 GB = 36 GB)
This morning when the user opened the C4R model, Revit crashed on open.
A look into the System Event Log turned up this note:
Grand Total 32,647,356,416 bytes = 30.40522 GB
After this crash I edited VM again per Optimize your Operating System for Performance to twice the size of installed RAM
65536 MB = 64 GB
VM then is 3 times RAM > 3(32 gb) = 96 GB
(Hope my math is correct)
I think this is perhaps a bit strong since the machines have 32 GB of RAM, but this looks to have been successful.
Any more insight would be great.
"Revit.exe (6684) consumed xxx-xxxxxxxx bytes"
I don't know how these x's got in there. There's something about this number that the forum's software doesn't like. I had to put commas in there.
Here's the revised event log entry:
"Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: Revit.exe (6684) consumed 30,096,269,312 bytes, Roamer.exe (9664) consumed 2239385600 bytes, and SavService.exe (500) consumed 311701504 bytes."
So... the paging file should be at least the size that is recommended for Windows and at most twice the size of installed RAM (According to Optimize your Operating System for Performance).
However, How to calculate RAM required for a specific project size in Revit... suggests that the required RAM is 20 x the model size.
What are you to do?
I venture to say one C4R Project we are working on is nearly 5 GB in size taking into account the links in the model.
5 GB x 20 = 100 GB.
Thoughts?
This is overkill!
The model is too big and needs to be broken up.
... probably needs to be 64 GB of RAM instead of 32.
