hello again,
finally, the error seems to come randomly and not related to the script in the patches we are dealing with about 20 different pix_share* but only one makes errors, we found a workaround : allocating a small memory space (1 1 1) on load and resizing it on the demand this works but this doesn't tell us why we got those shm_id error...
cheers
