After one of the OSSes is down, what sort of error messages do you get?
on stuck clients that do not try to access files from those OSSes?
Is it anything about problems contacting MDS by any chance?
There were some bugs fixed in 1.6.6 and 1.6.7 that could easy this
situation.
E.g. see bugs 13375 and 16006.
So perhaps consider upgrading your system and let us know if it still
does not work for you.
