[Lustre-discuss] ost_write operation failed with -28

[Brock Palen]

I had a client die with the following errors in dmesg:

Lustre: Client nobackup-client has started
standard.exe[4680]: segfault at 0000002ac4e88058 rip 00000033df807b7c

After abaqus segfaults, lustre throws some errors, but the mount is  
still useable.  The thing though is abaqus (standard.exe) has never  
died on us like this before on this input on this hardware (we are  
new lusture users).   Its a standard test case provided by abaqus.  s4b

I found no reference to -28  in google.
Any help would be great.
