I don't think this is necessarily an OOM, I had this happen again today and I don't see an OOM reported in dmesg. Instead I see this:
This happens often with a web site I've made into a Epiphany web app. It'll be sitting in the background and I'll go back to it to find it crashed.
I can't upload the data from the crash at the date/time above because this bug is closed (and Abrt thinks this latest crash is a duplicate of this bug). Let me know if you need it, it's still in Abrt.
The code in question is allocating with mmap:
void* result = mmap(0, bytes, PROT_NONE, MAP_NORESERVE | MAP_PRIVATE | MAP_ANON, -1, 0);
if (result == MAP_FAILED)
Note that it can happen if you still have plenty of system memory left, if the web process exceeds its 5 GiB address space limit (should happen around ~2.5 GiB of allocated memory, way more than should ever be required).
Reopening bugs that are probably caused by the address space limit....
