We have a MQ server on Solaris box. We have applications to put and get messages into the local queue of the queue manager. Applications take message from the text file and put in the queue. But at this point of time the first message always resulting an error
"Segmentation fault, Core dumped".
but not any error number or reason code and i did not find that error in either of the error logs of queue manager or var/mqm/errors.
But the second message onwards it is succeeding in PUT. What will be problem. is it a memory kind of thing? or is it relating to MQ only. if so any suggestion?
thanks in advance |

Hi Sneha,
I think your application is erroring out, am i correct
when its trying to put/get message to queue its throwing error,
is it C/java
If its happening on MQ, sure, you will get some error log, hope you have set kernel parameters for MQ as mentioned.

| We are using Q and QLoad applications of IBM for the purpose. How come it is able to put messages from the second one onwards? |

it looks like some kernel parameters is missing,
i suggest you to have a look of the same,
Qload/Q tool as well as MQ Series.

Sneha,
debug the core file..it will give you some information
http://publib.boulder.ibm.com/httpserv/ihsdiag/get_backtrace.html
A core dump is a snapshot of the memory occupied by a process plus additional debugging information. Core files are typically generated when a process terminates unexpectedly.
