[Box Backup] backup issue

[boxbackup@fluffy.co.uk]

I've been using boxbackup in lazy mode for a couple of months on our local
network to back up almost a dozen of servers. Everything worked fine, so I
decided to include some of the servers overseas into the backup process.

The first problem was the timezone - US timezones are 6-9 hours apart from
our
timezone, the second is the bandwidth (even though both networks have a 1Gbps
uplink, you can't get more than 250Kbps download for sucha distance) and the
third is the number of files/directories included in the backup - it's around
500000 files and 100000 directories.

The problem is, that after backing up 4GB out of 60GB of data the whole
backup
hangs and no new files get uploaded.

After a couple of days I decided to adjust the clock to be synchronised with
the bbstored server. This didn't help at all.
I tried the bbackupquery utility - has no problems at all, I can view the
backed up files and even restore them.
I tried to do bbackupctl sync -q it was hanging with no activity for more
than
24 hours.

This may be som major missconfiguration, but considering, that on other
setups
everything works fine, I decided to try the mailing list.

Here is the log from the client side:

And log from the  server:
bbstored[1425]: Incoming connection from <CLIENT IP> port 46001 (handling in
child 18214)
bbstored[18214]: Certificate CN: BACKUP-2000

(Probably
a network issue between client and server.) (7/34) -- terminating child


>From the logs it seems obvious that there is some network/certificate issue,
but I can login to the backup server using the bbackupquery utility.
