You have to repair your database and don't forget to optimize it. Which version of wordpress are you using?
Sometimes I also get fatal error when I continuously post one after another in my wordpress blog. But I don't receive the same error message like you. I haven't found this problem in earlier version of wordpress while posting continously. You also informed that you are using 2.6.1 version of wordpress. You should upgrade your Wordpress to 2.6.2 and I hope this problem will be solved.
i assume ur not using on webhosting services however ur own server? or else, ur hosting's set up has been pretty poor.. IMO. i prefer hosting company using cent OS linux.. urs seem to be very old user mapping system. as said above, it's memory problem... all u need is to reboot the system or let ur hosting admin to reboot it, i guess.
