Workstation Selective Restore issues with large backup sets

See discussion in german forum, mostly English re initial issue, now solved and ongoing issue displaying files and directories for restore when large backup sets are involved.

Bug 8271 has had other reports of same issue duplicated to it, if you can help go there

I have been able to use dar-manager from the cli to display the list of files/dirs that the selective restore produces to be displayed in server-manager. This included a 400+gb backup, this list in most cases is quite small, also dumped the output to a small file.  So the actual cli action seems to not produce an error even with the very large backup.

Small backup sets upto at least 100gb (limit of my testing) all display a list of files/dirs in the selective restore window of server-manager.

Backup set of 400+gb (all I have to test with) times out in displaying files/dirs in the server-manager window, a smarter person than I will find the why and we can fix it. 

The "pipe/process/whatever" that sits between the perl script and server-manager (apache or whatever) breaks with the bigger backup

See Bug 8271 there were a couple of other bugs that were dupes these have been closed and consolidated in this bug

Not yet, will go and do it now,

With a backup of 78gb, there is no issue using Edge, its just the larger backup that have a problem, I have one of 400+gb that suffers

Just tried to bring up the most recent inc file of the 400+gb backup

Ok, using Chrome, same problem, select the backup, perform, server-manager window "Workstation selective file restore" does not show files or dirs., and never shows that the process is even finished,

Apologies for suggesting more work, try latest Firefox, & try after a fresh restart of Windows.

As I have discussed with Terry, this may not have reared its head years back because backups were that much smaller. I doubt it was ever tested on 400gb !!

We may need a bit of a guru to look at this.
...
1. Read the Manual
2. Read the Wiki
3. Don't ask for support on Unsupported versions
4. I have a job, wife, and kids and do this in my spare time. If you want something fixed, please help.

Terry

Did you try changing the timeout setting as mentioned in the bug report ?
I would also suggest to change it to a much longer (10x more) value than suggested, just to see if that affects/resolves the issue.

All that, multiple settings, 600, 900, 3000, have watched the process run in htop, takes just on 8 minutes and that PID closes, no updates appear in server-manager window during or end..

There was a known issue back in early 2003, Apache bug https://bz.apache.org/bugzilla/show_bug.cgi?id=23528 patched in later versions, have tried the suggestions from there, nada

This  https://www.perlmonks.org/?node_id=809078 gives a hint but do not know who to do the code (perl) to add to the selective restore script to make it keep the pipe active while the script runs, and no it is not stderr that is the issue have dumped stdout and stderr to files from the cli stderr was empty
