application strucking up problem!

hello,

for my application, the application some times strucked for long time and I can't able to close the application window also.

It through,

1)IOException error and,

2)Unrecognized tag

errors.

In my application I am using SNMP. The IO exception occured at SNMPGetMIBEntry catch block.

But I don't know why Unrecognized tag error throws.

why my application hangs ocured.

Is it timer problem.
