[Help] AccountServer [Crash]

Hello everyone, so here is my concern my AccountServer.exe crash constantly when I look rpt file and I did a search in the map file I found this...:

Code:

0001:0001d1b0      ?Fetch@CBuffer2@@QAEPAV1@PAPAV1@KPAVCRC32@@@Z 0041e1b0 f   buffer.obj

then the file buffer.cpp I have this:

Code:

CBuffer2* CBuffer2::Fetch( CBuffer2** ppRecvBuffer, DWORD dwBytes, CRC32* pcrc )
{

    crc( pcrc );    // m_pcrc

    m_pTail        += dwBytes;
    ASSERT( m_pTail <= m_lpBufMax );
    
    int nRemnant;
    LPBYTE ptr    = GetReadableBuffer( &nRemnant );

    CBuffer2* pOld    = NULL, *pBuffer;
    u_long uPacketSize;

    DWORD dwCrc, dwDataSize;
    byte digest[4];
    u_long uHdrSize    = CBuffer2::GetHdrSize( (BOOL)pcrc );

    while( 1 )
    {
        if( nRemnant < (int)( uHdrSize ) )
        {
            if( cb > 0 ) {
                pOld    = *ppRecvBuffer;
                pOld->m_pTail    -= nRemnant;    // remove remnant from old buffer
                pBuffer    = new CBuffer2;
                
                ASSERT( pBuffer->m_pTail + nRemnant <= pBuffer->m_lpBufMax );
                memcpy( pBuffer->m_pTail, ptr, nRemnant );
                pBuffer->m_pTail    +=    nRemnant;
                *ppRecvBuffer    = pBuffer;
            }
            return pOld;
        }
        else

if someone could help me it would be nice
