DEBUG - Error Creating New Session

Often I'm told that the phpbb_session table is full and I must empty it manually to make the site work again. I don't know if you have my same problem, anyway here is the patch (that will be included in phpbb 3)

OPEN:

Code: [Download] [Hide]

include/sessions.php

FIND:

Code: [Download] [Hide]

            message_die(CRITICAL_ERROR, 'Error creating new session', '', __LINE__, __FILE__, $sql); 

REPLACE WITH:

Code: [Download] [Hide]

$error = TRUE;
 
if (SQL_LAYER == "mysql" || SQL_LAYER == "mysql4")
 
{
 
   $sql_error = $db->sql_error($result);
 
   if ($sql_error["code"] == 1114)
 
   {
 
      $result = $db->sql_query('SHOW TABLE STATUS LIKE "'.SESSIONS_TABLE.'"');
 
      $row = $db->sql_fetchrow($result);
 
      if ($row["Type"] == "HEAP")
 
      {
 
         if ($row["Rows"] > 550)
 
         {
 
            $delete_order = (SQL_LAYER=="mysql4") ? " ORDER BY session_time ASC" : "";
 
            $db->sql_query("DELETE QUICK FROM ".SESSIONS_TABLE."$delete_order LIMIT 50");
 
         }
 
         else
 
         {
 
            $db->sql_query("ALTER TABLE ".SESSIONS_TABLE." MAX_ROWS=".($row["Rows"]+50));
 
         }
 
         if ($db->sql_query($sql))
 
         {
 
            $error = FALSE;
 
         }                    
 
      }
 
   }
 
}
 
if ($error)
 
{
 
   message_die(CRITICAL_ERROR, "Error creating new session", "", __LINE__, __FILE__, $sql);
 
}

Re: [Patch] Error Creating New Session

ok, for 1 month this solution work, but now my website have more than 1200 users and the error appear again.

I believed that the solution is

Code: [Download] [Hide]

ALTER TABLE phpbb_sessions MAX_ROWS = 9999;

because of 2500 register are reached easily in my website in this moments.

my question now is this?

when my website grows again, this value was small again.

what is the maximum value than I can set up

thanks

EDIT:

AND waht about this table phpbb_sessions_keys¿???

i can truncate this table too, or if I do that, I will have troubles??

Convert it to MyISAM.

I've edited the code to Icy Phoenix.
Anyway you may even decide to convert the table from HEAP to MyISAM.
HEAP type has the advantage to remain loaded in memory, so SQL are a bit faster, but MyISAM should not have the problem listed above.
I use MyISAM...

I don`t know how do that.
but now, I ask,
in the final version(1.1.0.15) you do that(myISAM table??)
in the final version I need apply this patch???(in the first topic)

jeje my forum around 1800 users now

On a clean installation sessions table is MyISAM. I won't convert tables with the upgrade script, because it may leads to some problems if not done properly. ____________ Luca SEARCH is the quickest way to get support.
