Apache does not start due to bad group name

When I logged onto a server to clone an EBS instance from production, it gave a message

id: cannot find name for group ID 148.

"id" command shows group name is missing.
$ id
uid=1172(ebsdev) gid=148() groups=148(ebs)

I ignored the message and completed the clone. After that, Apache service did not start and even did not create any log files in $LOG_HOME/ora/10.1.3/Apache folder. The only error is in $LOG_HOME/ora/10.1.3/opmn/HTTP_Server~1.log :

apachectl startssl: execing httpd
httpd: bad group name 148

I realized where the problem came from and asked Linux Admin to fix the Group name issue.

$ id
uid=1172(ebsdev) gid=148(ebs) groups=148(ebs)

Then, I replaced 148 with the group name in file $ORA_CONFIG_HOME/10.1.3/Apache/Apache/conf/httpd.conf

User ebsdev
Group ebs

I also verified file /etc/group is READable. After that, I started Apache without problem.
