How to run 10+ agents at the same time while sharing resources?

Hey guys, I have OpenClaw connected to Telegram using a supergroup with topics. I have one development agent, but I've split my work into 10 different topics (one topic per app I'm building or maintaining). I usually send a prompt in one topic, switch to another while it's working, and keep doing that. As my number of simultaneous conversations increases, I've noticed that sometimes the agent just stops responding entirely in some topics. It won't continue until I send another message (even just a "?"), after which it suddenly picks the conversation back up. My guess is that everything is running on the same server and sharing the same Chromium instance or other resources, causing requests to get stuck. How are you guys handling higher workloads? Do you run multiple OpenClaw instances, separate browser sessions, different queues, or something else? For reference, I'm running everything on a 16 GB Hetzner VPS. I'd love to hear how others have solved this. Thanks!
