[Kernel-packages] [Bug 1319244] Re: iostat: Cannot open /proc/stat: Cannot allocate memory

2014-06-09 Thread Stephane Bakhos
Alright the test kernel clearly fixed the issue.

My gut tells me that there might be some memory leak also at play with
the non patched version, but I don't know kernel code well enough to
analyze that.

Unfortunately I'll have to bring the computer down tomorrow morning as there is 
a planned power outage.
I'll setup the patched kernel on the 2nd computer that is affected by the issue.
