[Gluster-devel] 3.6.8 crashing a lot in production

[Joe Julian]

To satisfy this curiosity, however, ubuntu 12.04's 
libc6-2.15-0ubuntu10.5 produces:

objdump -r -d /lib/x86_64-linux-gnu/libc.so.6 | grep -C 20 _int_free | 
grep -C 10 cmpxchg | head -21 | grep -A 3 cmpxchg | tail -1 | (grep '%r' 
&& echo "Your libc is likely buggy." || echo "Your libc looks OK.")
Your libc looks OK.
