Application Crashed

[psr1410]

I developed a Symbian WRT widget for Nokia. Its working fine. But Some time My widget is crashing and closing the application. Don't know why? I'm getting the error "WidgetUi - KERN-EXEC - 3", and some times "Posserver E32User-CBase42". This error I got in Nokia RDA 5800 Xpress Music Device. After the Error Message Application Was closing.

Below is the .cpp file While creating SIS

#include <e32base.h>
#include <e32std.h>
#include <SWInstApi.h>
#include <SWInstDefs.h>
#include <f32file.h>
#include <aknutils.h>
#include "WgzInstaller.h"


static const TSecureId KInstallerSID = 0x101F875A;
_LIT( KWidgetInstallerDir, "c:\\WgzInstaller\\" );

//TODO: Use your widget name here
_LIT( KWidgetInstallerFileName, "mysample.wgz" );


LOCAL_C TBool isProcessRunning()
{
TFullName res;
TFindProcess find;

while( find.Next( res ) == KErrNone )
{
RProcess ph;
if (ph.Open( find ) != KErrNone)
continue;

TSecureId secId = ph.SecureId();
ph.Close();

if (secId == KInstallerSID)
return ETrue;
}

return EFalse;
}


LOCAL_C TInt getPath( TDes& path ){

RFs iFileSession;
TInt err = iFileSession.Connect();
if (err != KErrNone)
return err;

//Read the name of the widget package
TFileName widgetFileName;

widgetFileName.Append(KWidgetInstallerDir);
widgetFileName.Append(KWidgetInstallerFileName);

path.Copy(widgetFileName);

TFindFile findFile(iFileSession);
findFile.FindByDir(path,KNullDesC);

path = findFile.File();
iFileSession.Close();

return KErrNone;
}


// Global Variables
GLDEF_C TInt E32Main()
{
// Create cleanup stack
__UHEAP_MARK;
CTrapCleanup* cleanup = CTrapCleanup::New();

// get wgz path
TFileName path;
getPath( path );

//wait while process installer doesn't stop running
while( isProcessRunning() ) {
User::After( 1000000 ); // put thread to sleep for 1 second
}

SwiUI::RSWInstLauncher iLauncher;

if (iLauncher.Connect() == KErrNone)
{
iLauncher.Install( path );
iLauncher.Close();
}

//Now we can delete the directory with the temp installation files to free up memory
RFs iFileSession;
iFileSession.Connect();
CFileMan* fileMan;
TRAPD(err, fileMan = CFileMan::NewL(iFileSession));
if(!err)
{
fileMan->RmDir(KWidgetInstallerDir);
delete fileMan;
}

iFileSession.Close();

delete cleanup;

__UHEAP_MARKEND;
return err;
}


Can any body help me regarding this issue? Where I'm doing Wrong.
And also I'm using Platformservices for geolocation and ApiBridge for Camera.

Plzzzzzzz
