Errors when pausing an experiment

Hi,
when trying to pause an experiment that accesses the core (here the CorePause form the examples) by another experiment that also accesses the core, I get the following error (interrupting the CorePause experiment by one that does not access the core works fine):
INFO:worker(2031,CorePause.py):print:main kernel loop running...
INFO:worker(2031,CorePause.py):print:kernel exiting
ERROR:worker(2031,CorePause.py):root:Terminating with exception (ConnectionResetError: Core device connection closed unexpectedly)

CorePause experiment (submitted with priority 0):
`from time import sleep
from artiq.experiment import *

class CorePause(EnvExperiment):
def build(self):
self.setattr_device("core")
self.setattr_device("scheduler")

@kernel
def k(self):
    print("kernel starting")
    while not self.scheduler.check_pause():
        print("main kernel loop running...")
        sleep(1)
    print("kernel exiting")

def run(self):
    while True:
        self.k()
        self.scheduler.pause()`

and the interrupting experiment (submitted with priority 1):
`
from artiq.experiment import *

class zotinoLED(EnvExperiment):
def build(self):
self.setattr_device("core")
self.setattr_device("dac") # this is the zotino dac device

@kernel
def run(self):
    self.core.reset()           # Clears the core
    self.dac.init()             # Initializes Zotino
    delay(1*ms)                 # Delay
    
    self.dac.set_leds(255)      # turn on all leds (led = 11111111 in binary)
    delay(3*s)                  # All leds will stay on for 3 seconds
    self.dac.set_leds(0)`

I'm out of ideas how to fix it, help is very appreciated.
