The problem was caused by a hand tuning parameter "kern.maxdsiz" in loader.conf. In practice, some programs need very large memory footprint. To make them happy, I increased the max data segment size by hand. Sadly, this made cmucl/sbcl crash. If I comment out the line in loader.conf, everything is ok now. The price is I have to constantly tune the kernel knob back and forth when needed. :-( Is there any good suggestion to overcome it? Thanks for all those who has kindly lend me a hand. best regards qxb -- ... there have been two really clean, consistent models of programming so far: the C model and the Lisp model. These two seem points of high ground, with swampy lowlands between them. --Paul Graham
