Subject: bug? corrupted revision?

Hi SVN users

I found a new error - (at least new to me):
....svnsync: REPORT of 'http://server/repo': Could not read chunk size: connection was closed by server (http://server)

We have the standard master/mirror repo setup as described in the Red Bean book. The sync is kicked off by the post-commit hook script. Today we noticed the sync was stuck on rev 768 on this repo (oddly it was 3 revs behind by then) so I gave the usual svnsync sync command and after a few rows of "....." I got the error posted above.

We recently (within a month or two) upgraded our Sparc-Solaris svn servers from SVN 1.6.9 to 1.6.16.

Usually we don't have sync issues with our many repos but revisions where the revs/?/?? file is near 100M or more does seem to timeout somewhere and we have a workaround that involves a dump/load of the overly large revision. (The file /Svn/repos/db/revs/0/768 is only 44M) I tried to create an incremental dumpfile for this revision 768 but I get another odd error:
[]> svnadmin dump /Svn/repos -r768 --incremental --deltas > dmp768
svnadmin: Can't read file '/Svn/repos/db/revs/0/361': End of file found

Yet oddly - the revision before and after 768 work just fine for creating a dumpfile:
[]> svnadmin dump /Svn/repos -r767 --incremental --deltas > dmp767
* Dumped revision 767.

[]> svnadmin dump /Svn/repos -r769 --incremental --deltas > dmp769
* Dumped revision 769.

The actions of revision 768 was the addition of a completely new folder to the trunk and contents for that folder. There is no relation between 768 and anything that existed in history in revision 361 or any other revision.

I did a svnadmin verify and it was fine until it got to rev 768 - but it complained about rev 361:
[]> svnadmin verify /Svn/repos
* Verified revision 0.
* Verified revision 1.
...
* Verified revision 359.
* Verified revision 360.
* Verified revision 361.
* Verified revision 362.
* Verified revision 363.
...
* Verified revision 765.
* Verified revision 766.
* Verified revision 767.
svnadmin: Can't read file '/Svn/repos/db/revs/0/361': End of file found

**Note** there are actually 770 revisions on this repo - but the 'verify' operation died on rev768 - while complaining of rev361.

I'm attempting to run a checkout of this repos' trunk directory to see what happens, (using TortoiseSVN). So far so good, but it is a very large repo and checkouts tend to run overnight. I'll follow up with those results in the morning.

In the meantime - what's up with my repo rev768? Is the repo salvageable?

Thanks,
Krista
