Debugging Distributed Mode

communication error -6

(tsdb::tsdb :cpu :jacy :file t)
initialize-cpus(): `merlot' communication error [-6].

This normally means that the hostname is wrong. Check using pvm what hosts pvmd thinks are available. A common mistake is to use merlot instead of merlot.domain.county or the other way round.

communication error -7

(tsdb::tsdb :cpu :jacy :file t)
initialize-cpus(): `merlot' communication error [-7].

Check that the path to the grammar, cheap instance and so on are correct. Also that cheap and tsdb are linked to the same version of the pvm libraries.

client exit for 'user'

(tsdb::tsdb :cpu :jacy :file t)

[t40002] BEGIN
[t40002] Reading ...
...
[t40002] EOF
  wait-for-clients(): client exit for 'user' <262146>
NIL

This probably means that cheap has died! Try calling cheap as: cheap -tsdb language.grm to see if it is working properly in tsdb mode. This was a common problem in 2004.

parse-interactively(): error `maximum number of active sessions exhausted'

If after loading your grammar, the parser, the transfer grammar, and the generator, you encounter such in error then it might be that your ~/tmp directory contains some old rubbish .pvm files that need to be removed manually.

• Remove any .pvm files and restart your logon process and try again.

Keyboard Freeze

If you are using SCIM as an input mode (the default for recent Debian and Ubuntu), then the keyboard may freeze when you try to type in the podium.

Three fixes:

• Set /FrontEnd/X11/Dynamic = true in ~/.scim/config Note that you may have to stop scim first, as it ovewrites the file when it stops

• Use scim-bridge

sudo apt-get install scim-bridge

• edit /etc/X11/xinit/xinput.d/scim

  change GTK_IM_MODULE=xim to GTK_IM_MODULE="scim-bridge"

  restart scim: scim -d.

• switch to using uim

sudo apt-get remove scim scim-bridge
sudo apt-get install uim uim-el
