[RTnet-users] Segmentation fault in 'rtnet stop'

[Teresa Noviello]

Hi,
we have two host:

-slack 9.1 kernel 2.6.15 rtai 3.3 rtnet svn snapshot (today snapshot)
-slack 9.2 kernel 2.6.15 rtai 3.3 rtnet svn snapshot (yesterday evening snapshot)

Now the phase of "Waiting for all slaves/Searching for master" is done, and we can see Stage1, 2 and 3 in the slave host (the control then return to the shell in the two hosts, normally).

But, when i do

'rtnet stop' in the

slack 9.2 kernel 2.6.15 rtai 3.3 rtnet svn snapshot (yesterday evening snapshot)

i have error.

Depending on the "rule in the communication" that the "slack 9.2 kernel 2.6.15 rtai 3.3 rtnet svn snapshot (yesterday evening snapshot)" host has, i have different errors.

WHEN slack 9.2 kernel 2.6.15 rtai 3.3 rtnet svn snapshot (yesterday evening snapshot) IS SLAVE.

I lose shell control. On the video i also have the message

"rtnet: line 248: 2660 Segmentation Fault"

-------------------

Any Ideas?

The problem in only in the SVN version? the snapshot of yesterday evening is so different from today snapshot?
