RTC run too fast

[pedja089]

Hi,
I have PIC18LF46k80, with 32768Hz crystal on SOSC pin. i need 32 interrupts per second for other things.
Shematic:

PCB:

ISR:
DEFINE  INTHAND myint  
#CONFIG
    CONFIG SOSCSEL = LOW ;Low power mode SOSC
    etc...
#ENDCONFIG
    TMR1H = 252
    T1CON = %10001101
    T1GCON = 0
ASM
myint
        Clrf BSR
        Btfss PIR1,0 
        GOTO End_RTC
        Clrf PIR1
        Movlw .252 ; TMR1H=252
        Movwf TMR1H

        Bsf _PULL

        Movlw .141
        Movwf T3CON
        Movlw .255
        Movwf TMR3H
        Movlw .223 
        Movwf TMR3L
        Bsf _TimeChanged,0
        Incf _Ticks,F

 
        Movlw .31  ;if ticks=32 then
        Cpfsgt _Ticks  
        GOTO End_RTC   
        Incf _Seconds,F
        Bsf _TimeChanged,1 
        Clrf _Ticks
        Movlw .1
etc...

I think that problem is in capacitors for crystal. I upload schematic and pcb layout, it's probably ok, but...
I tried to put capacitors from 10,12,22pF and result always is same. About 10s to much per day...
PC clock(Internet time disabled) and mobile phone are my references.
Any idea how to solve this??
Thanks

Maybe this help ?!

That is problem.. Because I can't sped few days adjusting cap...
I remove C6, now clock are much slower... C5 is 22pF...
I put 12pF on C5, and I will see result tomorrow.
Is both capacitor needed or just one?
