I've seen this happen twice in the full-2.3 builder.
I suspect it is related to #337 (test_process error).

Here's another failure for the same test, from the freebsd slave:

My guess is that the reactor doesn't have time to clean up after itself.
Here's a patch which should fix the problem:

I tried the solution, lets see if it helps.

comment:5 Changed 13 years ago by moshez

It seems this problem (and 337) were fixed.
Let's give it a couple more tests, and close it.

comment:6 Changed 13 years ago by moshez

This bug, and 337, seem gone.
Please open new issues for intermittent failures if they show
up again.
