…out delays Previously, session validation used pullResults() which would block for up to 2 seconds when no results were available, causing Cherry Studio and other clients to timeout. Changes: - Replace blocking pullResults() validation with time-based expiry check (25 min threshold) - Add lastAccessTime tracking to CommandSessionBinding for efficient validation

问题描述
在使用 Cherry Studio 作为客户端连接
arthas-mcp-server时，出现了严重的延迟问题：ping请求）都会延迟约 2 秒notifications/cancelledwith reason "Request timed out"mcp-inspector中不会出现，仅在 Cherry Studio 中出现根本原因
通过日志分析发现，问题出在
ArthasCommandSessionManager.isSessionValid()方法中：commandExecutor.pullResults()来验证 session 是否有效pullResults()是一个长轮询设计，当没有结果时会等待最多 2 秒（ResultConsumerImpl.pollTimeLimit = 2000ms）ping等简单请求，由于没有新的命令结果，会触发完整的 2 秒等待
