Hi Taher,

I did not find something specific.

The message I try to convey is this is an external random condition, not related to Buildbot or our script but the network+servers context.

 From time to time (more often since the date I put in the Infra Jira, but I can't see a relation with changes then in our script and it was happening 
before also) the tests fail and when I manually restart the same build they pass.

So for me it's not due to our script, which is only starting the tests, but to another conditions(/s?) on the network+servers context. Note that we 
use 3 test servers.

Note also that it happens that the "svn up"' phase fails. I once asked Gavin and he the told me that in such case I simply have to manually restart 
the tests...

That's when I learnt how to do it and that's what, among other things but mostly, I want to document

Thanks to care!

Jacques
