windows线程运行一段时间一直停在sleep被阻塞, 谢谢各位大佬

1. 在windows部署个项目, 线程每隔一段时间同步一次数据, 但是运行一段时间就一直停在sleep, 查看状态被阻塞 , 其他的线程也被BLOCKED

while (true) {
            try {
                //全量同步: 取完queue配置, 同步结束
                //增量同步: 循环配置里的内容
                conf = busiBlockingQueue.poll(5000L, TimeUnit.MILLISECONDS);
                //log.info("conf = {}，busiBlockingQueue.size = {}", (conf == null ? "null" : conf.getBusiType()), busiBlockingQueue.size());
                if (conf == null && transType == TransConstants.TransType.FULL) {
                    break;
                }

                //同步数据并处理数据
                try {
                    //是否成功获得同步标识
                    BusiTransVo busiTransVo = buildTransVo(transType, conf, sessionInfo);
                  
                    transDataService.dataHandle(transType, conf, busiTransVo, sessionInfo);
                } catch (Exception e) {
                    log.error(e.getMessage(), e);
                }

                
                if (transType == TransConstants.TransType.INCR) {
                    busiBlockingQueue.put(conf);
                    Thread.sleep(ConvertUtil.convertObjectToLong(conf.getBusiTransFrequency(),2000L));
                }

            } catch (Exception e) {
                log.error(conf == null ? "Conf is null" : conf.toString());
                log.error(e.getMessage(), e);
            }
        }

线程被阻塞, 也未发现死锁
