Memory Block Free'd Twice Error

[trent]

Hi Bruce,

I've receiving this error message in the WebHandler.DeleteSession method which is causing my WebServer to crash all the time. There is code in the DeleteSession embed to cleanup some In-Memory tables and update the UserLogin MS SQL table:

Code: [Select]

  debug('Clean Up IMDD Files by SessionID')
  start(CleanupIMDD, 25000, clip(p_web.SessionID), 'ALL') ! This just loops through each In-Memory table, finds records that are related to the SessionID, adds the record ID's to a queue, loops through the queue and deletes the In-Memory rows that match

  debug('Update User Login Record for log off')
  p_web.OpenFile(UserLogin)
  ULG:SessionID = p_web.GSV('ULG_SessionID')
  p_web.SetSqlTimeout(UserLogin,net:on)
  If not access:UserLogin.tryfetch(ULG:KeySessionID)
    p_web.SetSqlTimeout(UserLogin,net:off)
    ULG:EndDate = today()
    ULG:EndTime = clock()
    ULG:EndMethod = 'Logoff'
    p_web.SetSqlTimeout(UserLogin,net:on)
    access:UserLogin.update()
    p_web.SetSqlTimeout(UserLogin,net:off)
  ELSE
    p_web.SetSqlTimeout(UserLogin,net:off)
  end!if
  USR:SysID = p_web.GSV('UserID')
  p_web.SetSqlTimeout(User,net:on)
  If not access:User.tryfetch(USR:KeySysID)
    p_web.SetSqlTimeout(User,net:off)
    USR:SessionID = 0
    USR:ComputerName = ''
    USR:SessionDate = 0
    USR:SessionTime = 0
    p_web.SetSqlTimeout(User,net:on)
    access:User.update()
    p_web.SetSqlTimeout(User,net:off)
  ELSE
    p_web.SetSqlTimeout(User,net:off)
  end!if
  p_web.CloseFile(UserLogin)

In the debug I see something like this:

[1672] [Net] [1] NetWebServer._GarbageCollector - SessionID = wpZUvNmXJ9fW0ZGjN2SBWfmKRvxdPH has expired.
[1672] [Net] [1] NetWebServer._GarbageCollector - SessionID = XVe404gW8qMsdqxA9rm3TPHSVwNPps has expired.
[1672] [Net] [1] NetWebServer._GarbageCollector - SessionID = NEW0ZvHhFgrWejFF0rnxDwlfHKExDG has expired.

[1672] [Net] [5] _NetAll._LoggingSetup - Initialisation
[1672] [Net] [5] _NetAll._LoggingSetup - Initialisation
[1672] [KLWS] 10:44:20 Clean Up IMDD Files by SessionID
[1672] [KLWS] 10:44:20 Update User Login Record for log off
[1672] [KLWS] 10:44:20 Clean Up IMDD Files by SessionID
[1672] [KLWS] 10:44:20 Clean Up IMDD Files by SessionID

And then the crash happens. I don't see the debug that is in the 'CleanupIMDD' procedure at all.

Do you have any ideas why this is happening?

Hi Trent,

Ideally your code should be in NotifyDeleteSession, not DeleteSession method.

Also, you do not have access to the SessionQueue at this point. So your line;
ULG:SessionID = p_web.GSV('ULG_SessionID')
should be
ULG:SessionID = p_web.SessionId

also
  USR:SysID = p_web.GSV('UserID')
needs to contain the Session value as the key, not the UserID. Since the UserID is unknown at this point.

If ULG and USR are memory tables, then I don't think you need to wrap the code in a Sql Timeout call.

Cheers
Bruce

Hi Bruce,

Sorry I didn't notice those mistakes! I've moved the code to the NotifyDeleteSession and changed it to:

Code: [Select]

  debug('Clean Up IMDD Files by SessionID')
  start(CleanupIMDD, 25000, clip(p_web.SessionID), 'ALL')

  debug('Update User Login Record for log off')
  p_web.OpenFile(UserLogin)
  p_web.OpenFile(User)
  ULG:SessionID = clip(p_web.SessionID)
  p_web.SetSqlTimeout(UserLogin,net:on)
  If not access:UserLogin.tryfetch(ULG:KeySessionID)
    p_web.SetSqlTimeout(UserLogin,net:off)
    ULG:EndDate = today()
    ULG:EndTime = clock()
    ULG:EndMethod = 'Logoff'
    p_web.SetSqlTimeout(UserLogin,net:on)
    access:UserLogin.update()
    p_web.SetSqlTimeout(UserLogin,net:off)
  ELSE
    p_web.SetSqlTimeout(UserLogin,net:off)
  end!if
  if ULG:StaffID
    USR:SysID = ULG:StaffID
    p_web.SetSqlTimeout(User,net:on)
    If not access:User.tryfetch(USR:KeySysID)
      p_web.SetSqlTimeout(User,net:off)
      USR:SessionID = 0
      USR:ComputerName = ''
      USR:SessionDate = 0
      USR:SessionTime = 0
      p_web.SetSqlTimeout(User,net:on)
      access:User.update()
      p_web.SetSqlTimeout(User,net:off)
    ELSE
      p_web.SetSqlTimeout(User,net:off)
    end!if
  end!If
  p_web.CloseFile(UserLogin)
  p_web.CloseFile(User)

The User and UserLogin are MS SQL tables. Will let you know how this goes tomorrow.

Regards,
Trent

Hi Bruce,

I'm still getting the memory error and also a GPF that seems to be coming from xFiles even though I don't use any xFiles objects in my WebServer. Maybe this is something in NT8?

Here is the GPF:

Any ideas?

Hi Trent,

Couple of hints from that GPF Report;

the GPF is on Thread 3. So this is presumably when the thread is either being constructed or disposed. (was ther more in the log? The lines starting with [n] (where n is a number) are the interesting ones, the ones starting with are less interesting.

the most common reason for a GPF when having xFiles is that you haven't set the settings on the Multi-DLL tab of the xFiles global extension correctly - in the Data DLL or this app. (or possibly in one of the other apps in your suite.)

Cheers
Bruce

Ok well...

The WebServer is just a single exe, not multi-dll.

Line 493 of ABFile.clw is the FileManager.FileCallBackInterface.FunctionCalled method.

Line 2923 of klws_FC1.clw is the end of the file.

Line 3642 of the WebHandler module is the end of the file.

The xFiles template options have 'Free Queues before loading' - could this be freeing something twice?

There was no more in the log, BUT there was another log for the stack trace that was gobble-dee-gook to me:

copy the debug runtime binary from \clarion\bin\debug into the app folder and then get the GPF again. That may flesh out the report below.

Does the GPF happen immediately with the first request, or does it take a specific request to cause it?

cheers
Bruce

Hi Bruce,

It takes a while for the GPF to happen, definitely not on first request.

Copying debug files now and will post when it happens again.

Hi Trent

I would be very interested in knowing if this problem was solved as I am having similar issues with my web server at the moment. Random crashes and lockups. I had put this down to problems with the IMDD, but am unable to prove this.

Kind regards

Mark

Hi Mark,

what backend are you using?

[Mark Sarson]

Hi Kevin

Topspeed at the moment, but moving to SQL when I can get the crashes out of the way.
