Bug Description

Using Bedrock I've started to repeatedly get the following messages after any interaction:

⎿ API Error (503 Too many connections, please wait before trying again.) · Retrying in 1 seconds… (attempt 1/10)

⎿ API Error (503 Too many connections, please wait before trying again.) · Retrying in 8 seconds… (attempt 5/10)

Steps to Reproduce

Seems to occur at any message.

Additional Context

I saw these infrequently earlier in the conversation but they started increasing in frequency - not sure if it's related to some Bedrock issue separate from Claude Code, or if Claude Code is hanging onto connections over time to Bedrock that accumulate the longer a session continues.
