Subject Re: DUCC's job goes into infintie loop
Date Mon, 13 Nov 2017 14:08:38 GMT
Several different issues here. There is no "job completion cap", rather
there is a limit on how long an individual work item will be allowed to
process before it is labeled a timeout. The default number of such errors +
exceptions before a Job is stopped is 15. Please increase this cap if you
expect a work item to go longer.

If a job process runs out of heap space it should go OOM at which point
unpredictable things will happen.  Do you see OOM exceptions in the JP

As for a bug, it is still hard to understand what is happening. Newer
versions of DUCC include a ducc_gather_logs command that collects DUCC
daemon logfiles and state and makes it more likely we can understand what
is happening. No user application logfiles are included in the captured tar
