If quick feedback is necessary, you would be wise to go through support (presuming you have an up to date entitlement), at https://www.redhat.com/apps/support/ - bugzilla is less for support than for bug fixes. Ah,good point. I'm just a kernel dev helping out on this issue and bugzilla is the standard interface for me. I'll advise the customer to take the support path (although the immediacy has past, at the moment they're happy backing up to the RHEL3U1 kernel), however I'll continue to follow and work this bug as normally done in my testing and development context. thanks So RHEL3-U1 did not show the slowdown? Thanks to your detailed report it is clear that the tg3 driver itself is not the problem, it seems to be something generic. Perhaps something to do with memory pressure. There is no way to reproduce this other than running Oracle? Correct, we never saw the slowdown w/ RHEL3-U1. I have not been able to reproduce the issue outside of the customer's setup (which I no longer have access to), but I haven't really tried too hard. If I get a chance later, I'd like to try to write a few test cases that may strain the system in the same way (large number of open connections, lots of processes, etc). Need addtional info from IBM. IBM need details here to proceed further. I'm still trying to reproduce this issue, however I've run into unrelated hardware problems. I'll update this bug as soon as I know more. I have not been able to reproduce this issue, so I'm going to close this. It can be reopened if it is ever seen again. |
