check the no. of process when you are trying to install any package from different terminal
like the one I did in mine
Code:
#yum install dhcp
(in progress)
on different terminal
Code:
#ps -aux | grep yum
ps -aux | grep yum
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ

root 10914 0.0 0.0 3892 660 pts/4 R+ 07:54 0:00 grep yum
Code:
#rm -rf /var/run/yum.pid 2902
and yum is working on both terminals simultaneously
