HI all,
I checked the profile file START and I noticed that the command line to launch the IGS was incomplete (I do not know why because I have not changed the start profile). I made a backup of the profile and I edit the START profile. After that disp+work proccesses don't start. Even after I have written files saved profile, system you do not start. In the dev_disp log I found :
