Hi Sage,
I just updated to debian-testing/0.50 this afternoon, after some hint:
* osd: better tracking of recent slow operations
and it is hereby confirmed to be better in my testing environment. Before I had requests, which could be there for >480 seconds… not any more.
How's about this fix in 0.48.X?
Thnx in @vance,
Oliver - Thus being too lazy to read all change logs - Francke.
