比特元节点，正常同步过程中程序突然假死，通过pprof分析系统协程数量不断上升

假死状态时， version， net is_sync, block last_header等命令可正常访问， mempool系列命令， net info卡死
手动Ctrl+C停止前台进程，程序没有退出，反而恢复为正常运行状态

目前追踪到假死时，协程间存在系统调用死锁，其中一个是写日志操作，导致整个系统所有写日志阻塞，由于mempool是单线程模式，和mempool交互的协程阻塞无法处理，即协程数持续增加

正常同步一段时间问题必现，目前环境是WSL下的ubuntu18.04，WSL1对linux内核支持不完备，大概是这个问题，后续保持跟踪
