</div>It is possible to simply raise the heartbeat timeout with:<br>
<br>
ipython notebook --MappingKernelManager.time_to_dead=10<br>
<br>
which will make it 10 seconds. Once you find the smallest value that<br>
works reliably for you, you can put this permanently in your<br>
configuration file.<br></blockquote><div><br></div><div>Yes, and if you are using master, the more relevant value to set is MappingKernelManager.first_beat. I get along fine with a time_to_dead = 0.1, as long as the first beat is long enough to wait for process startup.</div>
