MySQL Table not closed

Hi i run WordPress 1.5 every now and then my linux box where word press runs cashes. i get alot of harddrive activity and my linux box dose not respond. at first i thoug it was due to a lack of computer memory. but i have ruled this out recently.

i get some sort of system mail that i read i had 22 new messages most all were regaurding MySQL and word press php files.

apperntly the problem is some “tabels” were not Colsed” properly it apperntly happens when my site is accessed. it dosent happen all the time its accessed only sometimes.

any way it results in major hard drive activity and a frozen PC. I have to reboot and then all is fine.

any one have a similler issue ? or help me out on a place to start to look for a soltion to this problem.

heres my site- hopfully it should be up (unless MySQL has crashed it again)
