When the computer was in an idle state last night the following box appeared.

called Error -artsmessage.

Sound server fatel error

AudioSubSystem::handel0:write failed

len=-1, can_write = 4096, errno = 2 (No such file or directory)

This might be a sound hardware/driver specicfic problem (see aRts FAQ)

Any help would be appreciated.

After a re-start all works ok but it was difficult to shut down, it hung!! and needed to be forced to shut down.
