[Swift-devel] Sporadic connection handler messages in 0.95RC7

[Michael Wilde]

Mihael, All,

Im getting a sporadic "Could not start connection handler" message 
followed by a tracback starting at gssap code (see below) at the start 
of some test runs from bridled to beagle using 0.95RC7, coasters, ssh-cl 
and provider staging.  The message seems to occur on less than half of 
my tests and whatever is causing them doesnt seem to be impacting the run.

I intend to upgrade this script to trunk/0.96 as soon as time permits, 
but in the meantime, if you know the cause of this, it would great of I 
could fix it.  If not, its very low priority and not at the moment worth 
much of your time (unless it recurs on 0.96 and/or causes failures).

The runs are on bridled at /scratch/local/wilde/epsweep.

Thanks,

- Mike
