I'm using libcurl in LADP. I found the apache progress which named 'httpd' used 98% CPU. Then I used gdb attached the progress.
This situation lasted for 6 hours up to now. I readed the source of the function named 'Curl_llist_remove ()'.  I would think it's a infinite loop.
Er ~ ~ I'm sorry for my poor English and I'm a rookie. Oh! come on ~ please.  (^_^)
