If it is the kproc gil......here is a white paper for you to look at. Good luck :-)...

ITEM: CG7981L RISCO: What is the kproc gil?

WWQ&A Question:

We have identified a kproc named gil that is using a high amount of cpu on a wide node in our SP system. We are at AIX 4.1.4. Can you tell us what gil is, and under what circumstances it might consume a high amount of cpu? Thank you

Response:

The kproc gil runs the TCP/IP timer driven operations. Every 200ms, and every 500ms the GIL thread is kicked to go run protocol timers. With TCP up (which is ALWAYS the case), TCP timers are called which end up looking at every connection on the system (to do retransmission, delayed acks,etc). This wasn't seen on 3.2 because this work was done on the offlevel interrupt and thus was not a runnable process. In version 4 this work is all done on a multi-threaded kproc to promote concurrency and SMP scalability.

Basically the output for gil is incorrect. For example load average might give you 1.01 instead of 0.01 that you might expect.

We would suggest ordering ix52496 to fix the problem.
