Question

我开发了一个从MQInput获取消息的流，通过调用存储过程将其插入到DB中，然后将消息转储到另一个队列。消息在XMLNSC中。

流程处于运行状态2个月，但现在我遇到了奇怪的问题。

3天后我得到了这种例外：

当我收到此错误时，我知道内存已满，我停止了流程。一天后，我无法在代码中找到任何特定问题，并再次启动流程。

请注意，我记录的XML长度为6000行。

昨天我在跟踪中得到例外情况：

  (0x01000000:Name):RecoverableException = (
(0x03000000:NameValue):File     = '/build/slot1/S900_P/src/DataFlowEngine/MQLibrary/linklib/ImbMqInputNode.cpp' (CHARACTER)

(0x01000000:Name     ):Insert   = (
  (0x03000000:NameValue):Type = 2 (INTEGER)
  (0x03000000:NameValue):Text = '2' (CHARACTER)
)
(0x01000000:Name     ):Insert   = (
  (0x03000000:NameValue):Type = 2 (INTEGER)
  (0x03000000:NameValue):Text = '2056' (CHARACTER)
)

））

我无法找到根本原因。至于一个月，Debug程序工作正常，它在日志中写了整个XML，现在流程给了我异常的行为。此外，还为输入和输出队列配置了BOQ。

从上述错误中，有两种可能导致此错误。

QMGR文件系统可能已满。请检查/ var / mqm文件系统。如果您对此文件系统没有任何问题，请参阅第2点
队列文件的大小可能大于用户文件限制大小。请使用ulimit -f检查文件限制大小。并将其与队列文件大小进行比较。我怀疑这可能会导致你的问题。如果是这样，您可以使用'ulimit -f 4194302'（2GB）来增加大型队列的文件系统。

无法将消息放入回退队列消息代理
