Apache Camel Quartz RejectedExecutionException

Question

在特定时间运行quartz骆驼路线（cron-job）时，会生成约1MB的文件并将其上传到FTP。

它低于错误，并且是间歇性（有时直到过程结束我都不会出错）。 在本地无法重现该问题几乎成为不可能。但是，如果我尝试在进行中的cron-job中更新骆驼路线，则会抛出完全相同的错误，

我该如何解决？

错误：

编辑：

在分析日志时，我可以看到日志“从这里开始”，并且当它进入SomeProcessor.java时，也没有例外，但是日志“在处理器之后”没有打印。

SomeProcessor.java

Map<String, String> searchAttributes = buildSearchFilterAttr(exchange);
        Set<Order> orderSet = new HashSet<Order>();
        logger.info("fetching {}", searchAttributes);
        try {
            dataSet = cleint.someAPI(....);
            logger.info("total number {} ", dataSet.size());//300
            exchange.getIn().setBody(dataSet);
        } catch (IOException | BadRequestException ex) {
            logger.error("error");
            throw new SomeCustomException(errMsg, ex);
        }
