Research direction

Start with the reported stack trace at com.alibaba.polardbx.rpc.pool.XClientPool.getConnection and com.alibaba.polardbx.gms.metadb.MetaDbDataSource.initTsoServicesX. Reproduce the local startup using the main branch and inspect the X Protocol connection timeout to 127.0.0.1:32886. Done means identifying the startup failure cause and documenting or correcting the required local setup or behavior.
