Incompatible buildVersion jobtracker/tasktracker

I'm getting this "Incompatible buildVersion" error even though they look to be the same build version (see below). The only difference is that the tasktracker is running on Debian-6.0 and the jobtracker on Centos-5.3. Are there known problems with this setup?

Thanks in advance!
