This problem is on Tandem NSK. MQ 5.1 is installed. We have a java pgm which continuously polls on a local queue for messages. If the pgm finds any message it will process it and if no message available, pgm sleeps for some time(say 2 sec) and again looks into the queue. Getting the message by pgm is done under syncpoint. Probelm is, if there is no message available for a long time (say about 3hrs), pgm is abending with reason code of 2232. if the pgm finds message occassionally it's not failing.
here i'm giving the logic of the pgm.

class A{
static void main(){
classB.openqueu(localQ) //this method opens the queue in get mode
while(true){
tx.begin(); //Begin of Transaction
rcvdmsg = classB.getmessage(localQ); //gets the msg under syncpoint
insert the message in DB;
tx.commit(); //commit Transaction
}
closequeue(localQ) //closes the local queue.
}
}
ClassB{
openqueue(){

}
getmessage(MQQueue q1){
try{
getMessage(q1)
}
catch(MQException emq){
if the reason code is 2033 ignore the exception sleep for 2 seconds.
else throw exception
}
}
}
is this problem because, i have opened the queue for long time and doing nothing. Please advise.

Thanks,
Poorna
