The logged in user is a member of a group that has a write permission on a folder. But when this user is trying to write something, “permission is denied”.
The log below summarizes the question:
subv:/www/tracer/ whoami frank subv:/www/tracer/ subv:/www/tracer/ ls -ltr total 4 drwxrwxr-x 2 root tracer 4096 Jan 20 12:25 convert.tracer.com subv:/www/tracer/ groups frank frank : frank tracer subv:/www/tracer/ > convert.tracer.com/test -bash: convert.tracer.com/test: Permission denied subv:/www/tracer/
Output of “ls -bail /www/tracer/convert.tracer.com/”:
subv:~/ ls -bail /www/tracer/convert.tracer.com/ total 8 38010883 drwxrwxr-x 2 root tracer 4096 Jan 20 12:25 . 38010882 drwxr-xr-x 3 root root 4096 Jan 20 12:25 .. subv:~/

Method 1
Group membership is re-read on login. groups seem to report the groups you are in according to /etc/group and does not reflect membership of groups in the current session.
Use the command id -Gn to show the groups that you are currently an active member of. Solution: relogin to apply the group changes.
Method 2
What about the permissions of the directory where you have the file?
Are you able to edit the file, i.e. with vim, and save it?
Try to do something like
chmod g+w .
UPDATE
subv:~/ ls -bail /www/tracer/convert.tracer.com/ total 8 38010883 drwxrwxr-x 2 root tracer 4096 Jan 20 12:25 . 38010882 drwxr-xr-x 3 root root 4096 Jan 20 12:25 ..
It could there was an issue while creating the tracer directory, I see strange spaces between root and 4096 in the second line of your output.
I would try this as root:
cd /www/tracer/ chown root:root . chown root:tracer convert.tracer.com
If it’s still ok, I’d check the group name in /etc/group, doing a
cat -v /etc/group
Checking that there are not non printable chars in root and tracer group
Finally if you still have the issue could be SELinux or an issue with the file system.
