Dhananjay,

As a disclaimer, I am not interpreting the error log file that you posted. The single most common cause that I have found for crashing a RT target with Error Code 18 is for the RT system to run out of memory. You may want to look at the VI to determine how much memory it is using (VI Description>>Memory Usage). If you are allocating many arrays of large arrays of data, and you are not manipulating it effectively (causing extra copies of the data), it is very easy to overload the available memory of many of the RT targets.

Regards,

Aaron

Hello,

It is very likely that you are running out of memory.  If you do a search on our website, you can see that there are other reasons why you can get this error.  What RT target are you using? You can check the memory that it is been used through the Tools--> Real-Time System Manager.  It will let you check memory and CPU.

Hope this helps.

Hello,
Thank you Aaron and Ricardo....
Somehow,the application started working,maybe I tweaked the code a little bit,tho I cant put my finger on it.
The exception handler 18 has been giving me constant trouble.
There is also the description of the real time target in here...
