Putting 140 on an infinite loop (while(true); do ./test/etap/run test/etap/140-attachment-comp.t ; done) eventually gives me http://www.friendpaste.com/2JCA8dvre9orA3UysYYTCe on both SSD Mac OS X 10.6 and Ubuntu 10.04 on disk in a VMWare.
I also got one instance of http://www.friendpaste.com/7EpB1eJGRoRFBvjXvmFG3V on the Ubuntu. The first one comes up reliably after half a minute or so and repeats itself, it may well be a socket ulimit or something. The second one I only ever saw once so far. Cheers Jan --
