[SOLVED] Session Table Full error

[BMD]

I am getting the following error message when I go to my site.....

phpBB : Critical Error

Error creating new session

DEBUG MODE

SQL Error : 1114 The table '*****_sessions' is full

INSERT INTO ********_sessions (session_id, session_user_id, session_start, session_time, session_ip, session_page, session_logged_in, session_admin) VALUES ('cda0f924e07635d8ba0b094962fb5494', -1, 1194637581, 1194637581, '9d156568', -13, 0, 0)

Line : 200
File : sessions.php

This is the second time this has happened in the past week.

The last time it resolved itself.

Does the table clear a session once it is closed out? Logicaly you would assume that once a user left the site the session would be cleared.

I have noticed I am getting crawled by yahoo bots a lot now... sometimes 8 at a time.

Could this be causing the problem?... If so.. any suggestions on curtailing the bot traffic, so only one at a time is on the site at any given time?

Thanks in advance.

Cheers
Doug

I altered the path for obvioussecurity reasons .

I am going to reset the original seesions.php file for the time being.

if you copied this code exactly, and did not add empty lines after the php close tag, it will not produce those errors.

edit* it appears that you left off the php close tag

Code: Select all

 ?>

There were no lines following.... however there were 3 "Spaces" after the

*?php

and

?>

at the end of the .script...I removed those and all seems fine now
for the moment.

Thanks for the help.
