Client process aborted was reported only with the parent job

Enviroment: NBU 8.1.1 RHEL 6.5
Recently we had a long time standard full backup job running continuously with no any problem for hundred hours.
But after 196 Hrs the parent job done with status 50,  versus its child job(19018182) was still active running normally.

So:
1) How to understand such problem only failed with the parent job ?
2) What/which ever the client process aborted would mean about ?

Re: Client process aborted was reported only with the parent job

In most cases where NetBackup Client and NetBackup Server have been running a backup job quite well and quite steadily for many hours then it is usually quite likely for them to continue to do so until a sucessful end of the backup job is reached... unless... external factors cause a state change or interuption to an element of the communications path.  And, I'm sorry to say, that it will be nigh on impossible to determine which external factor(s) caused your backup job interuption unless you have a repeatable failure pattern.

Re: Client process aborted was reported only with the parent job

1)  But why the child job could be still running active until its success eventually  ?
2)  It was strange that all the child jobs have their own schedule & PID versus the parent job not!
     So where the client process of the parent job came from?

Re: Client process aborted was reported only with the parent job

When multi-streaming is not enabled then there is generally no concept of a parent and child job, i.e. there is a just a job.  When multi-streaming is enabled, then backup jobs are a set of a parent job (which has a "-" for schedule name) plus child jobs which do reflect the schedule name - and this is justa feature, this is just the way it is.

As for why child jobs would suceed, and yet the parent job fail with status 50, it is not possible to tell without detailed logs.

Re: Client process aborted was reported only with the parent job

I did see this in your log snippet:

02/22/2020 00:17:06.766 [Diagnostic] NB 51216 nbjm 117 PID:7969 TID:139759446025984 File ID:117 [No context] 1 V-117-238 [BPCRConnection::handleError] had an error, status=40

...and to me status 40 have always been really difficult to track down errors to do with LAN networking and LAN switching, and hardly ever due to NetBackup itself.

Re: Client process aborted was reported only with the parent job

1) But most backup types do have their parent job, such as Catalog、DB App,  so it should have nothing to do with the multistream.
