Martitza, do you have lightweight checkout?

As workaround you can change the working tree browser to classic style: main menu -> Tools -> Options -> Working Tree -> select "classic" instead of "qbrowse".

Yes. I am experimenting with lightweight cbeckouts. (Turns out they
mighT be ok fpr us if we organize our repos a little differently.). I
will try your suggestion today.

Another suggestion: use heavyweight checkouts, aka bound branches
instead of light branches, if you have enough room on your disk to
hold all your history.

Ok! Instead of my usual "huge" test branch, I've been working with a tiny
branch with only three files. So...

Sure enough, bound branches do not exhibit the Too ManyConcurrentRequests
bug.

So far, only checkouts are showing the TooManyConcurrentRequests bug.

To be clear: the bug occurs on Windows XP using bzr+ssh with bzr 2.2.0 and
bzr-explorer 1.1b1 for lightweight checkouts only.

I have not seen the bug on ubuntu (I have looked) but I am still running bzr
2.1.x on my lucid boxes.

Update and correction (cf. comment #6): I *do* see this bug on Ubuntu.
