Work process freezes when SE01/SE09/SE10 transaction executed.

Hi All,

When I call transaction SE01 or SE09 or SE10, the work process freezes.

In the process overview (transaction SM50), I can see that the program where the process froze is SAPLSTRF.

Please help me what might be the reason for the error and how to resolve.

Thanks and Regards,

Chandra.
