Hi all,

We seem to be running into the io-net consuming-all-CPU problem which is referenced in the following forum post.

http://community.qnx.com/sf/discussion/do/listPosts/projects.networking/discussion.technology.topc3292?_pagenum=10

We are running 6.3.2A with multiple devn-i82544 NICs.

Is anyone able to confirm the following questions urgently?
- Can you confirm this bug is present in 6.3.2A?
- Is there a patch or other fix available for 6.3.2A or do we have to upgrade to 6.4.1 to get the fix?
- In which of the following cases (specifically) does the bug occur?
A - Calling select() with a NULL timeval struct for timeout?
B - Calling select() with a timeval struct which is filled with all zeroes?
C - Calling ionotify() with _NOTIFY_ACTION_POLL?

Unfortunately the thread quoted above doesn't seem to answer these questions.

I hope someone is able to answer these questions as it is killing us at a major customer site at the moment.

Thanks in advance,

Rob Rutherford
