Hello Marcel,
I have exactly the same setup in 5 installations and all work fine, except one were Postgres often crashes with log "FATAL: out of memory" error which is caused by a Windows Server (NT Level) exception 0xC000012D "Out of Virtual Memory"...
The Conquest version is 1.5.0 and runs on a Windows Server 2019 Virtual Machine with 4vCPUs, 12GBRAM, 100GB OS Drive, Postgres12 on top of a DELL / Vmware ESXi 6.7 host.
I have observe that quite often (almost daily) we get Warning Level events in Windows Event Viewer that dgate64 consumes significant Virtual Memory such as the one I copied below.

I have tried to increase Virtual Memory space manually in Windows system advanced setup but in vain.... It eats all you give.
Any ideas of what is going wrong ? Is it hardware problem... RAM maybe ? disks ?....
I repeat that it happens only in 1 case out of 5 installations.
PS. The rest 2 virtual memory hungry tasks that appear in the above event are Windows Defender and MSSQL server
Best regards.
