is carte server run out of memory. carte server jetty server pdi functionality, java process it's nature wich run jobs or transformations. jobs , transformations it's nature description of carte server should do. fetch data, sort string, have been configured. if want run massive tasks of carte server have tune carte startup script give java process more memory, more heap space, define best gc strategy or ever based on knowledge on have tuned. try google on 'gc overhead limit exceeded' , play java process startup arguments.
