The test requires a lot of memory on my 64bit Linux box. Two of three times the test process was killed by the Kernel's out of memory manager although I have 8 GB physical RAM and 4 GB swap. Can you rewrite the test to use less memory? _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
