<p>Good morning,</p>
<p>I have people reporting crashes off and on, but unless I have
detailed information<br>
on why JNOS crashed, it's hard to provide a fix. It is important
to know why JNOS<br>
crashes, then I can get it fixed, and everyone benefits.</p>
<p>This is a simple procedure. If you are experiencing JNOS crashes
more then<br>
you care to deal with at times, then you can run the GDB debugger
in another<br>
terminal while JNOS is running already. The procedure is
documented below :<br>
<br>
1) Get the PID of the jnos process, using the linux command :
</p>
<pre class=""> ps -ef | grep jnos
2) Once you know what the PID is, then run the gdb debugger as follows :
gdb -p pid
3) GDB will load, JNOS will hang temporarily, and GDB will give you a prompt
at which you should enter the following command :
continue
Then both GDB and JNOS will continue to run again.
4) When a crash occurs, GDB will break out to the prompt again, and JNOS
will hang. Take a screen shot of what GDB printed out, then enter following
command at the GDB prompt :
where
You can also try the following command after that :
back full
Note ALL info that appears, even the JNOS console might have some stuff.
Please send all of that information to me, with a brief explanation of what
might have been going on at the time.
5) If you have JNOS logging in effect, please send me the log file, starting a
little before the crash time, so we can see what might have led up to it.
Thank you, much appreciated. Hope you are all doing 'okay'.
