Few questions for you: Are both your clients and servers running 3.2.29? Where did you build the OrangeFS kernel module?
Does this lockup happen consistently or randomly? Do you have available the client logs and syslogs corresponding to this error? If so, please forward those.

Our current setup: orangefs-2.8.6 with patch to stable svn revision 9510 and 3.2.29 vanilla kernel. Users experience hangs of various commands while using pvfs2 directories, e.g. ls hangs indefinitely until killed with SIGKILL. After such error happens I can't remove pvfs2 kernel module: though all fuser or lsof detected processes are removed, usage count is still 1. I see a lot of kernel BUG messages in the kernel.log, for all of them IP is kmem_cache_alloc. See full text in the attached file. I will update to 2.8.7 + latest stable branch and for 3.2.43 kernel and will report back after some testing. Another question: any progress on kernels >= 3.4 support? 3.2 became quite old these days. Maybe in the upcoming OrangeFS-3.0?
