Mark Nuttall commented on ARIES-974:
------------------------------------
Hi Guillaume,
We've recently started seeing this deadlock in our build environment. I'm not
familiar with this area of the code, but may need to dig into it anyway. Have
you by any chance had a look at this problem all ready? Do you have any
thoughts on what might be happening?
Regards,
Mark
