SIGPIPE failure - How do you diagnosis cause?

Code: Select all

APT_CombinedOperatorController(1),2: Unexpected termination by Unix signal 13(SIGPIPE)
Right now, the best method I could do to diagnosis SIGPIPE failures are to eliminate all possible warning messages (even column propagation warnings at times can be fixable).

But I am at a loss at how to further diagnosis the actual cause of this cruelity to innocent processes by the big bad UNIX. Doing the above stuff would just make this message go away... without really understanding what in the job caused it.

So I'm calling out to the rest of you guys -- How do you deal with SIGPIPE failures? What do you do to diagnosis the cause to eliminate this error showing up again?

T.J.,

What are the output messages for the other "APT_CombinedOperatorController"s?

Also, have you tried turning off the combined operators env var? That would be a good step in debugging this error.

Enlarge the scratch area and ensure adequate page space. At least 1x physical memory. The reading process for a named pipe has been killed, probably space issue.
Disable operator combination with "APT_DISABLE_COMBINATION=1", force compile, run again.
