Integration engine is red

Hi Guys,

Well i m looking for some help. We have XI 7.0 installed here on Linux 2.6 and Oracle 10g. The problem is the Integration Engine is red. our communication channel is working fine, no errors, no jobs failed, so i stuck here to find out the reason. I have restarted the server too, butt still the same.

Kindly help me how to find out the reason for that.
