RFC call having problem while calling from webdynpro

Question

Hi ,
I am facing a strange problem .In my webdynpro i have a RFC function module . the structure is like this.
Loop.
<GET current system>.
TRY.
call <RFC FUNCTION MODULE> DESTInation <own system> .
ENDTRY.
ENDLoop
With in the Function module we have created  a BDC seesion.
Here the loop is running for 10 times .for the first time it is the rfc call is perfect and a session is created in sm35.
For the second loop run the system is going to hang.and when i checked sm35 the next day 1 session is created (for the second loop)
Like this the session are created in different days .And the session created times are like00:00:04,00:00:08 etc.
I have checked if any hold time is there for the session but there is noting like this .
And i digged more and checked in SM50 there the call is running in background and it is connected some other system though i have given the target system as own system.
please advice me about this and how to find the root cause for this.
thanks

Thanks for your reponse .
Here the problem is it has already been developed now the Bug is the function call is still running and the sessions created as
below
17.06.2010     00:00:30     SAPMSSY1
17.06.2010     00:00:28     SAPMSSY1
16.06.2010     00:00:36     SAPMSSY1
15.06.2010     01:21:46     SAPMSSY1
15.06.2010     00:59:33     SAPMSSY1
15.06.2010     00:01:06     SAPMSSY1
Now teh problem is why the sessions are not created at the same time i executed it.ie,on 11:06:2010.
so,please let me know why is call is taking that much long time .(it is very rare for RFC call for such a long time ).
