I checked in logs as well but there is no useful information regarding this
error.
Anyone faced this kind of issue before. Please let me know how can i fixed
this kind of issue.

Strange apache2 ports are listening :

root@d101:~# netstat -lntp | grep apache2
tcp        0      0 0.0.0.0:8010            0.0.0.0:*
