[rhn-users] shared memory and hyperthreading

[espen.ekeroth at om.com]

Our application is not running to well on RH ES 3.0 with the SMP kernel - it
seems to be a problem with the hyperthreading and shared memory or signals. The
application is stable on RedHat 9 and RedHat ES 3.0 with the EL kernel.

Is there any special items I should be aware of when moving an appication from
kernel 2.4 to 2.6 or moving to a hyperthreading CPU?

The application is written in C, and the program is compiled on a Compaq
Proliant 360 - P3 running RedHat 9.0 with gcc-3.2.2-5 (std installation -
nothing special). Deployment on Compaq Proliant 380- P4 running RedHat ES 3.0.
