I tried to identify segfault (core files) and I did not find them
for i in `find / -name core -print 2>/dev/null` do
file $i | grep "core file" >/dev/null
if [ $? -eq 0 ]; then
file $i
fi
done
/root/core: ELF 64-bit LSB core file, x86-64, version 1 (SYSV), SVR4-style,
from '/usr/lib/vmware-tools/sbin64/vmtoolsd -n vmusr', real uid: 0, effective
uid: 0, real gid: 0, effective gid: 0, execfn:
'/usr/lib/vmware-tools/sbin64/vmtoolsd', platform: 'x86_64'
Is there any another way to identify these segfaults which are mentioned in
/var/log/message file? To check which is their problema cause.
