phpBB : Critical Error

Error creating new session

DEBUG MODE

SQL Error : 1114 The table 'phpbb_sessions' is full

INSERT INTO phpbb_sessions (session_id, session_user_id, session_start, session_time, session_ip, session_page, session_logged_in, session_admin) VALUES ('5719aa3b652f68118be5b3e47da91671', -1, 1220082909, 1220082909, '55e54c80', 0, 0, 0)

Line : 187
File : sessions.php

Förstår dock inte så mycket php i kodform, så här ser filen ut som ligger på servern, kan någon vänlig själv hjälpa mig:

På något webbhotell? Kontrollera så att du inte använt all tillåten disk / databas-utrymme.

Inlägg av **Holger** » 2008-08-30 17:41

Eh, är det inte bara att tömma sessionstabellen? phpbb_sessions alltså.

Inlägg av **tumba25** » 2008-08-30 19:40

Tittade i php-filen och hittade ingen begränsning där.

M.Anton · Inlägg av **M.Anton** » 2008-08-31 07:16

Problemet löste sig självt efter en stund.
Men det verkar komma tillbaka varje morgon numera?

Hur tömmer man en sessionstabell då?

Inlägg av **Marcus** » 2008-08-31 13:00

Det görs ju automatisk (då det finns en tid för varje session).

Men vill du göra det manuellt kan du göra det i phpMyAdmin. Kommer väl troligen inte att uppskattas av alla som blir utloggade när du göra det.

Ang. webbhotell, vad har du och är det så att du ligger på gränsen till maximalt utnyttjande. I phpBB finns det inget tak för t.ex. hur stor din sessiontabell kan bli.

Har ditt webbhotell en "storlek större", så är det kanske idé att uppgragera till det.

Men asså, är det bara jag som inte kan logga in menar du?

Nu har det löst sig igen, udda

jag har efter sökande här på forumet konstaterat att jag måste kontakta webhotellet vilket jag nu gjort, Surftown har vi samt deras Expert version.
Hittade dock till phpmyadmin men eftersom jag suger på databaser så lät jag det vara, hade hoppats det skulle vara nåt enkelt (i mina ögon sett)...

Jag har iaf kontaktat webhotellet och kollat hur det ligger till med trafiken, vi uppgraderarde precis, http://www.vwpc.se/forum

Tack för all hjälp.............
