Hi all We are testing lfc-mkdir command, from our UI works fine, if we try: /opt/lcg/bin/lfc-mkdir -p /grid/cesga/asimon/test3 but if we put this line into a script and we submit it we got this error: t3218970304:p26528: Fatal error: [Thread System] GLOBUSTHREAD: pthread_create() failed [Thread System] insufficient memory (ENOMEM) Curiously if we run directly this command on a WN using the same user certificate this command works without errors. Has anybody already detected this problem? Thanks in advance Alvaro
