Hi,

One of the jobs I was running on Terra failed after about 168hrs (this job is expected to take long time) with following error

"Task PC.PCAir:NA:1 failed. The job was stopped before the command finished. PAPI error code 4. User specified operation timeout reached" 

But I don't have any User specification in my WDL or as an input. 
Could you help me on this issue?

Thanks,
Seunghun Han

  Hello Seunghun,

  There is a global, absolute limit on how long a PAPI VM can run, which is most likely 7 days which is why the task failed at the approximate 168 hours (1 week). We believe the source of the “user specified operation timeout” refers to PAPI’s role as a user of Compute Engine.

   

  You can try to do some parallelization of the task to help reduce the runtime so it does not hit the limit.
