The skimage autopkgtest usually, but not always, fails on armhf with several out-of-memory errors
BTW "out-of-memory" errors nearly always relate to address space rather than actual memory. The Linux kernel overcommits memory by default, so actually running out of memory is more likely to result in the OOM killer killing your process than an out of memory error. You can of course outright run out of address space (possibly because of leaky tests), but more subtuly you can get issues with address space fragmentation, where there is sufficient space available overall but the alocation algorithm can't find a block big enough to satisfy your request.
