</div>I don't know why but in many OpenVZ VPS /dev/shm is not mounted automatically. I suppose that they prefer to keep it disabled for some security reasons (every user could use this space for writing) and let the system administrator mount it.<br>

<br>
I'm very sorry to get back to this only as late as I do now... My apologies. Thank you for the patch!<br>
<br>
I would consider, that often the issue is that, while /dev/shm might be mounted, it might still not be mounted read-write.<br>
<br>
That said, however, I'm uncertain whether an additional test for os.access('/dev/shm/', os.W_OK) would be appropriate, as I myself run no LXC/OpenVZ type of "virtual but not actually virtual" virtualization.<br>
<br>
If you could help me understand what this actually means / would actually do, I'd be more than happy to accept the patch and/or make the additional adjustments.<div><div class="h5"><br>
