freezes with "Postprocessing uploaded data"

[Polarbear-j]

Happened twice today. first case was harmless since all <100 objects were uploaded already.
Second case was >100 objects (which is my chunk size). Seems to be JOSM- and not API-related since no http request remained open.

Progress window stuck with message:
"Postprocessing uploaded data ... (1/2) Uploading 100 objects ...[cancel]"
pressing cancel does nothing. Application becomes unresponsive

The changeset shows 9 ways + 91 nodes uploaded (i.e. my first chunk of 100).

Had to press ctrl-c in the controlling terminal, which caused the shutdown.
Remaining 66 uploads were in the recovery file, so it could be repaired with solving some conflicts.

If this happens again, can you use visualvm (should be included in your java distribution) to get a stack dump?

[michael2402]

Closed as duplicate of #14765.

[Polarbear-j]

Ok, sorry for the dup. I had been searching for 'postprocessing', while #14764 used 'post-processing' and 'uplift' and #14765 'uploading'.

Meanwhile I went for visualvm.github.io, when running it told me that my JRE is not enough, so I got the JDK, which includes jvisualvm and jstack already. So we are prepared ;-)

Apparently I have to wait for the next nightly, as the fix is in 12101 and downloads still has 12092?

[michael2402]

It's no problem to post this, it is often hard to see which ones are the duplicates.

Yes, you need to wait until the next nightly comes. As a workaround until then, you can disable the authors panel on the right (just hide it).

I have still the same bug: ""Postprocessing uploaded data" freeze
version 12450

Did you have a chance to run jvisualvm and get a stack trace?
