I've seen your report about this, but haven't had much time to follow
up on it.
When exactly does the system "hang" as you describe - when you click
the "Apply" button on the disable form ? Or before the form ever
appears ?
When I click on Apply or OK on password form
Does it hang also if you use the disable function from the "info"
column page ?
Only from info column page
If you do a "ps" listing of the processes spawned by Apache, is there
a "hobbit-enadis" CGI running when this happens ? If there is, could
you add "--debug" to the hobbit-enadis.cgi command in
~/cgi-secure/hobbit-enadis.sh and let me know what that reports when
you hit the "Apply" button ?
Nothing, only hangs!
Also, you can try killing the hobbit-enadis process when it hangs with
a "kill -6 PID" - that should make it core-dump, although I'm not
quite sure where this core file ends up since it runs as a CGI
script. You may have to add a "cd /tmp" in the hobbit-enadis.sh CGI
wrapper to get it to core-dump in /tmp. If you find such a dump, it
would be interesting if you could get the stacktrace:
Core was generated by éhobbit-enadis'.
