loss of committed changes

we have seen a few incidents where a committed change gets lost, and in
at least one case lost repeatedly. In searching the archives for this I
noticed a post that seemed to be describing the same thing I have seen:


relevant text:

>> You forgot to actually declare dav_svn_get_repo_name.
>> dav_svn_repo_name is static, so that doesn't belong in the header
(it >>isn't
>> in there, but is in the commit msg).

>Not sure why I have lost that change several times. Fixed though.


If, by saying that, Ben is saying that he committed a change and it
disappeared, we're seeing that--a lot. We noticed an isolated case here
and there in the past, but yesterday when bunch of developers were
working, often in the same file, we would see changes disappear quite

Here is the sequence:

     developer A commits, changing file Foo.pl

     developer B updates, getting developer A's changes to Foo.pl,
     running Foo.pl and seeing the results of those changes

     developer B commits, changing file Foo.pl, but not near Developer
     A's changes

     2 lines that Developer A committed are no longer there now, even
     though Developer B did not remove them.

We also had a line get doubled (i.e. the same line of code appears twice
in the file), and I've seen the change-reverse behavior above with an
add/subtract pair of lines as well.

In another incident yesterday, Developer A committed, Developer B svn
upped and saw Developer A's changes come in, Developer C svn upped, but
didn't see Developer A's changes come in.

Has anyone seen anything like this? (I would love to provide you with a
shell script to reproduce, but at this point we don't have it pinned
down. It seemed to be a lot more prevalent yesterday with multiple
people working at once on the same files.)
