Is it possible that somebody from the Apache Infrastructure can
provide a view on which URL the traffic load was soo high that the
servers got in trouble?
POST requests to /ProductUpdateService/check.Update file
I am currently investigating the server logs and will post my results
later.
The trouble causing HTTP POST requests found in the server logs does not
seem to be related to the update function in former OOo versions.
I have investigated the update function HTTP requests from various
former OOo versions in the server logs. All of them provide content for
the HTTP UserAgent field. All of found HTTP POST request does not have
such data.
Looking at some sample HTTP requests from one IP address reveals that
the HTTP requests from the update function are unrelated to the HTTP
POST requests.
I investigated the HTTP traffic of update function from former OOo
versions (OOo 2.2, OOo 2.3, OOo 2.3.1, OOo 2.4, OOo 3.x). None of these
showed an HTTP POST request.
I evaluated some server logs from days before the established redirects
from INFRA-5112. Here, I could not found any of such HTTP POST requests.
My conclusion is that there were another function in OOo which causes
these HTTP POST requests. OOo 3.2, OOo 3.2.1, OOo 3.3 does not seem to
have such a function, because the redirects for their update functions
had been established a couple of weeks ago and I did not found any HTTP
POST requests.
how curious... thanks for the update and continued good luck with the
investigation
In order to figure out what is going on here, I will follow up with
Apache infrastructure. I will report on ooo-dev, when I know more.
Best regards, Oliver.
