iDirect x3 error : rebooting - order allocation failed ??

From email:
I have x3 rebooting with this message: _alloc_pages: 0-order allocation failed ( gfp=0x1d2/0)
Occurs every 5 - 10 minutes.

Do you have any idea of cause ?.

If so, please email me eric@satsig.net and include reference 26/10/2019 16:56 and I will tell the person asking.

Thanks.
