Hi
Running MBv7 on Linux
We have the PID of the DataFlowEngine process
But trying to retrieve OS ThreadIDs for each specific Message Flow deployed in that Exec-grp
We are experiencing CPU issues. Know what OS thread is causing the problem. But trying to figure out the Message Flow name for that particular ThreadID
The message flows only perform WebServices. Otherwise I believe I would have figured out a way to find the OS threadIDs from MQ queues.
I have captured Broker Service, User traces. Not much useful
Can you please suggest the way out? Thanks in advance ! |

| I would try to kill the thread while tracing. I think you should be able to see from the trace which flow gets restarted. Supposing you can kill an OS thread. |

| Service trace should include thread id information. |

Hi,
I wonder if you can divide you flows to separate eg:s?

Thanks all for the responses
Service Trace contains Thread info. But the ThreadIds obtained in the trace are not matching the ThreadIds captured at the Linux OS level (ps –AlLMF)
Even the syslog entries contain ThreadId but they dont match with the ThreadIds obtained at the OS level.. Not sure whats going on
Asked Sys-admin (root) to kill the thread. Kill was unsuccessful
JCNs are not an option at this point. Trying to do this w/o modifying the flows
Is there any other way to approach this ? |

You could stop all flows one by one and check each time if the problematic thread remains in place.
But I guess this is your production environment and this approach may be a little difficult to follow... |

Unhelpful.
Not least because the OP indicated Linux not Windows.
