Hi,

Problem :-

We are facing problem of core dumps and abend files created in Integration Node error directory /IBM/MQSI/common/errors.
This happens when we placed a file in a directory and FileNode tries to pick it up and the file got locked in mqsitransit directory.

Scenario :-

At first occurance of placing the files, when the file gets picked up by FileInput node, the debugger ends abruptly when trying to enter into further compute node placed after fileinput node. and file got locked and reside in mqsitransit directory.

Deployment Artifacts :-

We are using IIB 10.0.0.2 Runtime as well as toolkit. We have prepared applications and multiple shared libraries. One shared library (A) is referencing second shared library(B) and also A is referencing some JAVA projects. (A) is having subflows which are using Java compute node also. B is having common schemas. There are applications which are referencing this shared library (A).

So when application is deployed , A is also getting deployed alongwith its referenced jar files. There are few external jars also which are placed in IIB Node shared classes directory ( /IBM/MQSI/config/<NODE NAME>/shared-classes. IIB flow calls some JAVA classes method which are deployed as war files in weblogic server.

Abend Files content some part :-

******************************end
We are not able to find the root cause after reading this abend file.

This is not restricted to msgflow which is having fileinput node.
This is also replicating for msgflow starting with MQInput node. In this case , the msg is read from the queue but again the debugger ends abruptly and abend,core dumps starts generating repeatedly.
We have recreated fresh Node, servers in node and try redeploying after cleaning, but again problem persists.

We have applied service trace as well but there nothing concrete we found . We suspect there may be some issue with java classes loading/access within the IIB environment, but not sure.

Can you please suggest where can be the problem.

Thanks
