I have seen this sort of thing, and I think the cause is that it is
taking SVN a long time to put together the transaction and, during that
time, no data is going through the HTTP pipe and the connection times
out. I am pretty sure the Apache setting to change here is "Timeout".

Hello Team,
I use Subversion 1.13 in Ubuntu 20.04.5 LTS and sync a
repository size of 300GB to a mirror server ( same version of SVN
and OS ).
I get the following warning svnsync: E120106: ra_serf: The server
sent a truncated HTTP response body every time ( I had to take a
dump of specific revisions and load it in the mirror server ).
Did anyone face this problem while in sync? Is there any solution?
Do you see any common pattern with the revisions causing trouble?
Possibly if they are very large or contain a lot of files.
This was mentioned once before on the list [1]. I don't see if the
user found a way around it, but he mentions that the troublesome
revisions were large imports.
Kind regards,
Daniel

I have seen this sort of thing, and I think the cause is that it is
taking SVN a long time to put together the transaction and, during that
time, no data is going through the HTTP pipe and Apache thinks the
connection is idle and kills it. I have seen this both with svn and
user checkins, in the latter case the checkin contains thousands of
changed files. I was able to see this in action by looking at what
files were changing within the (replica) repository itself and I could
see files in "transactions" (or was it "txn-protorevs"?) and I could see
them slowly growing as each change was written into them.
I am pretty sure the Apache setting to change here is "Timeout". There
may be other settings I am forgetting about, it has been some time since
I have seen this.
It is possible there may be some filesystem tuning which could speed up
the file writes, but I have no direct experience with that.
