Re: [ferret_users] spawn stops working

Hello all,

Thanks so far for all suggestions given at the beginning of the month.
Maybe this won't get solved, as the problem occurs sporadically for no
apparent reason.

Exactly: it happened again today, after a long time.

No, /var/log/messages doesn't produce anything as a consequence of
using the SPAWN command.

Same problems for the SPAWN() function (suggested by Patrick).

Karl suggested it may be my bash scripts (that's the shell I'm using).
It shouldn't produce output.  It sources /etc/bashrc, set aliases and
shell variables.  It also runs unicode_start(1) and xmodmap(1); I
excluded those (will run only on my workstation now).  Furthermore, it
sources a bash script that reloads the the Modules package ferret (the
rest of that script is just directly setting shell variables).

Since the problem does not occur often, it is difficult to troubleshoot.
