I think it somehow related to apache seesion because after I remove all 
the sessiondata in /usr/local/rt2/WebRT/sessiondata, everytime works normal.

I am using:
Red Hat Linux release 7.3 (Valhalla)
RT ver 2.0.13
Server version: Apache/1.3.27
mysql  Ver 11.18 Distrib 3.23.53a
Browser: Internet Explorer 5.0 or above, Netscape 6.0 or above, Opera

Many Thanks,
