Describe what the problem is?

When I run Ogmios using docker-compose I can get the node and Ogmios to sync, but I get "out of memory" heap errors when pulling from the node repeatedly using the RequestNext mini-protocol. I'm running on 16 gigs of RAM. I used to be able to run my code with Ogmios in the past usingv3.2.0, however that version also produces errors now when syncing, i believe due to the older node version. Is there a higher memory requirement needed to run Ogmios?

What should be the expected behavior?

Pulling data using RequestNext without memory heap errors.

Hello thanks for reaching out. This is quitr surprising as Ogmios does not require much memory by itself. May you answer the following questions to help us pin-point the problem:

• How many clients connection are you opening? Single one or many? If many, how many?
• Are you sure the error is coming from Ogmios or does it come from cardano-node?
• Do you have an idea of both processes heap sizes? (assuming you only have Ogmios and Cardano-node running as services on the machine).
• How did you obtain the executable? Compiling from source with stack, Nix or using docker?
• Are you using any custom runtime flags?

Thanks!
