<p>Thanks for the hint about /var/log. Indeed, you are correct as
the OOM (Out of memory) error is there:<br>

<div dir="auto">Sounds like it was an OOM error [1]. There should
be something in the system logs (e.g. /var/log). Since OOM
handling is performed by the kernel it is not simple to trap
this.<br>
