run top command and check the apache threads for any continuous cpu or memory usage. if it is not responding then it might be busy processing something unnecessary.

That is also looking fine.  Interestingly if I restart Apache it works fine for sometime. Again it starts behaving eratic. Do you think we should try upgrading/downgrading

that is an option you can try. also you can try putting some watch on the apache using some monitor program. you can also try some cron to monitor the tcp activities may be that can lead somewhere.
