solana program close still freezes Surfpool block production on v1.0.1 and fails to close program #575
Description
Environment
Surfpool version: 1.0.1
Solana CLI: 2.3.10
OS: Ubuntu (WSL2)
RPC: http://localhost:8899
Description
When running solana program close against a Surfpool validator, the transaction fails with:
Error: Close failed: RPC response error -32002:
Failed to process transaction: receiving on an empty and disconnected channel
After this error occurs, Surfpool stops producing blocks (~400ms block production halts) and the validator becomes stuck. The RPC becomes unresponsive and the Surfpool process must be restarted.
This appears to be the same behavior originally reported in Issue #454, which was supposedly fixed in PR #457. However, the issue still occurs in Surfpool v1.0.1.
Steps to Reproduce
Start Surfpool
Deploy an upgradeable program
Attempt to close the program
solana program close GFr2d7PgU5QHHrpjpsV2iWb1wH4N19Ud7R5KaiUzuEh3
--bypass-warning
--url http://localhost:8899
