Yeah， I use gdb --args /usr/local/bin/python ../xxx.py --core xxx.core Then, 'run' to start script. However, the core dump file is actually from a memory leak process,which use 1.2 G momory, but now, through info proc, I got proc id, and then, shell pmap proc_id, only 650M, so, seems this is new started proc, not reload env from the core file. Anything wrong? Thanks. Wesley -- https://mail.python.org/mailman/listinfo/python-list
