all i do is run the server and at random times it locks up and pings out causing restart

What version are you using?

im sorry should have stated that. I have cb 1.4.2 r3.0 with nolagg 1.89.0 . I was using the standard sqlite db for ps. Lest night i changed it over to our mysql and transfered the db there and so far no errors. i think the db had an issue or corrupt. but if it happens again today when im on it i will repost
