Can some one tell me what does this mean:

Interrupt:21 Memory:f7fe0000-f8000000 

This is showing in output of ifconfig. The issue is i have a service (memcache) which is not responding on the machine. When i checked i found the above msg after tx and rx line for eth0.

machine is dell optiplex 980.

Thanks and Regards.

Server Fault is a better place for this kind of questions. – dschulz Jul 5 '12 at 13:59
See the other comment by @dschulz, but it's only telling you what interrupt line and memory resources are in use by your network interface and its associated driver. Most likely has nothing to do with any memcache issues, especially if your network interface is working for anything else at all... – twalberg Jul 5 '12 at 14:40

The Interrupt number is the IRQ number used by the CPU and NIC to communicate across the bus. The Memory range is probably the address range used for DMA communication with the NIC. These are both low level hardware configuration values, and are very unlikely to be relevant to memcache not responding.
