2233766 - Backint backup hanging during backup of Nameserver Topology

Symptom

When performing a backup using Backint, the backup of the nameserver topology in SAP HANA Studio does not show any progress.
Thread information in HANA Studio may look similar to the following:

Port	Service	Thread Method	Thread Detail	Thread Status
30001	nameserver	Request	core/stat	Running
30001	nameserver	JobWorker	Backup::BackupExe_Job	Semaphore Wait
30001	nameserver	JobWorker	Backup::BackupExe_Job	Semaphore Wait
30001	nameserver	JobWorker	Unnamed-PipeChannelJob	Sleeping
30001	nameserver	Request	BackupManager	Job Exec Waiting
30001	nameserver	Request	_IDX_BackupExecutor	Semaphore Wait

The “Sleeping” thread Unnamed-PipeChannelJob shows the following call stack:

1: __nanosleep_nocancel  
2: usleep  
3: Execution::milliSleep  
4: Stream::WritePipeChannel::triggerOpen()  
5: Stream::PipeChannel::triggerWrite  
6: Stream::PipeChannelJob::run  
7: Execution::JobObjectImpl::run  
8: Execution::JobWorker::runJob(ltt::smartptr_handle<Execution::JobObjectForHandle>&)  
9: Execution::JobWorker::run(void*&)  
10: Execution::Thread::staticMainImp(void**)  
11: Execution::Thread::staticMain(void*)
