Came across a glibc bug which could've caused some corruptions. On googling about possible problems, we found that there is an issue (https://bugzilla.redhat.com/show_bug.cgi?id=1305406) fixed in glibc-2.17-121.el7. From the bug we found the following test-script to determine if the glibc is buggy. And on running it, we ran it on the local setup using the following method given in the bug:
----------------
# objdump -r -d /lib64/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.")
7cc36: 48 85 c9 test %rcx,%rcx
Your libc is likely buggy.
----------------
Could you check if the above command on your setup gives the same output which says "Your libc is likely buggy."
