Hello!
I’m able to build my level on UE4.11 but not on UE 4.12 preview 5 because this error on a PC of the “farm” (only 2 PC).
I’m not able to build my level with one computer (It seems that the max pagefile.sys for 16Gb of RAM is 27Gb) because my computer crash with saying it has not enough resources (something like that).
Hope is the good agent log…

Hey Metathesus,
Try cleaning and validating your Swarm Cache to see if that helps at all. Could you provide me with your ‘dxdiag’ so I can take a look at your system specs?
I would also take a look at the Swarm Agent Troubleshooting Guide to see if there is helpful information in there as well.
Thank you,
Hi Andrew!
I have 2 clients computers ( 1 server and 2 clients), same symptoms on all clients computers!
The swarm log show (pretty sure it’s related) :
[PostJobStatsToDB] Database error:
[PostJobStatsToDB] Une erreur liée au réseau ou spécifique à l'instance s'est produite lors de l'établissement d'une connexion à SQL Server. Le serveur est introuvable ou n'est pas accessible. Vérifiez que le nom de l'instance est correct et que SQL Server est configuré pour autoriser les connexions distantes. (provider: Named Pipes Provider, error: 40 - Impossible d'ouvrir une connexion à SQL Server)
My english Translation to help you is:
An error linked to network ou specific to the instance has occured when establishing a connexion to SQL server. The server is not findable or unreacheable.. Check that the instance Name is correct and the SQL server is configured to accept distant connexions (provider: Named Pipes Provider, error: 40 - Unable to open a connexion to SQL Server)
Depending of “I don’t know what”, the virtual memory start to be full, leading to computer crash (Sometime the server, sometime the clients… (It’s a big level, one computer is unable to build it alone because not enough memory (16Gb max)
Checked twice my firewalls, make a sfc/scannow, drivers are up to date.
Of course I have clean all the agents swarm cache and validated like you suggest.
I’ve read the troubleshooting guide. Since I used the network build, I’ve had two issues that have lead to bug reports with an UE-xxxxx
Note: I’ve imported from 4.11 a fully build level in 4.12. In 4.12 I need to rebuild lights (412 objects) , It’s related to a BP with loop to create instanced static meshes (and I’m not sure to landscape?)
I will try to remove parts of my level to see what elements are leading to the crash and I hope i will be able to send a light crashing version of my project.
Bad connection, unable to send the whole project.
Hi!
I haven’t been able to find what causes the problem!
It’s a medium/big sized level (with sub levels) which need a lot of memory to be build.
Unreal lightmass (now 4.12 released) seems to use more memory when building lights (??? Swarm agent is the same version ???)
I’have been able to build with reducing the number of cores used (remote for client and local for server)… but why? what the relationship between core and memory…
When I build light in 4.11, the agents use only RAM, with 4.12 they use a lot of swap (pagefile.sys becomes very fat (SSD killer…))
Perhaps this documentation can help explain how Swarm Agent distributes and uses memory. Unfortunately, there isn’t a whole lot of documentation on Swarm Agent so identifying exactly the issue without having your set up is going to be difficult.
Let me know if you are still stuck or have further comments.
Cheers,
