A 2Gb swap file. It could be that the first newline in this file is far from the beginning, I've deleted it since. > For chkrootkit, I guess checking for fixed string (at least when we can > expect long greps) is sufficient and would fasten it a lot. It was in fact checking for fixed string when it nearly stopped my machine, the invocation was `grep php'. I see that since grep usually prints out matching lines, it needs to allocate enough memory for the current line. Thanks for pointing that out. I guess this bug becomes a wishlist bug against chkrootkit. Regards, Laurent. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
