Hi,

We have a job, where we are reading the data from complex flat file, doing some transformations in transformer, doing aggrgation and writing into the dataset. However the job aborts and give error as "operator terminated abonormally received signal SIGSEGV". This error we get after transformer. Could someone suggest as what exactly this error is?

Thank You

Do an internet search for "SIGSEGV" (segmentation violation) then tell us about what memory-hungry operators are mentioned in your score.

Well, I dont understand what you are asking for, but throgh google serch i found that this problem is because of the memory is unallocated or unmapped by the OS. It can also be because of Invalid Permissions for mapped objects. I dont know what eactly to check in the job. Will APT_DISABLE_COMBINATION = TRUE will help here?

this might also be the issue
if there are more number of stages in a job

or in transformer the stage varibale logic is not handled correctly for decimal ,number datatypes i.e claculations

There are many possible reasons why you (your job) may have tried to access a memory address to which it is not entitled. That's why I asked you to search - there is no point trying to guess what your particular cause is. APT_DISABLE_COMBINATION will assist your diagnosis only if the error is being thrown by APT_CombinedOperatorController.
