We are getting below error message sometime.

Aggregator_1,0: Operator terminated abnormally: received signal SIGSEGV
main_program: Unexpected exit status 1

In this job we are using 2 Aggregator and 1 Join stage ...

Please tell me reason of this error and how to solve.

Make a copy of the job and remove the second aggregator and join stage (I am assuming that your first aggregator is called "Aggregator_1"). Recompile and see if the error is reproduceable. If yes, then please post some information on what you are doing in the aggregator. SIGSEGV is a segmentation violation error that is caused when a program gets confused about memory addressing and this can occur in innumerable ways and doesn't help too much in localising your problem. Also, do a "reset" of your job and then look at the log entry "from previous run..." to see if that helps narrow down the cause of your problem.

code is like this :

Both aggregator stage starts from 2 ds then output of aggregator is input of Join then this output is redirecting to final ds.
