the server was running for a few without any more allocation
failures with kernel 2.6.32.29 but at one point the server
stopped responding, it was still possible for a while to
get a login, and trying to kill some processes but that
didn't succeed.  But after that even login was
no longer possible so we had to reset it.
I attach the call trace, I hope you can find out what is
the problem.

thanks,

   Peter
