Ah, OK, I see it now in the old logs. There are no such lines in the
latest logs.

Yes. I'm attaching full log (with timestamps and IPs removed) for a
certain period of time around 4th January. There are plenty of E175002
errors without any subsequent 'Corrupt node-revision' part, including
all the latest entries (not part of the attachment).

I was wrong about that. I was only checking the latest error log where
all I get is

[dav:error] [pid 42289] [<IP>:29011] Unable to deliver content. [500, #0]
[dav:error] [pid 42289] [<IP>:29011] Could not write data to filter.
[500, #175002]

But I've found those additonal errors in an old (archived) log. At the
moment I'm unable to reproduce the error 'Corrupt node-revision' both
on the client and in server logs, but the repository is still
misbehaving.

Server version: Apache/2.4.7 (Unix)

I'm not sure how to check MPM. I get

> httpd -l
Compiled in modules:
  core.c
  mod_so.c
  http_core.c

but "httpd -V" as suggested on some websites doesn't work. How should
I check which MPM is being used?

The repository is stored on a local disk. I'm not sure what about
filesystem is it that you are asking, but here are some possibly
relevant data:

> cat format
5
> cat db/fs-type
fsfs
> cat db/format
6
layout sharded 1000

(and before I upgraded the repository, db/format was 4). Is that what
you were asking or do did you want to know something else?
