I don't see this on a bigger Dell with the same software versions. I wonder if this could be related to running on an Atom cpu in combination with Fedora's optimization flags.
mozalloc_handle_oom() - It looks like the box it running out of memory.
It is a little machine with only 1 GB memory, but normal operation and running firefox works just fine and there is plenty of free swap space. It is only the logout from that page that consistently fails. It seems strange that it should need so much memory for that. That would look like a bug to me. Running firefox with strace shows that it terminates after: 4055 mmap2(0xf0dea000, 4096, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xad1ff000 4055 madvise(0xf0dea000, 4096, MADV_NORMAL) = -1 ENOMEM (Cannot allocate memory) 4055 munmap(0xad1ff000, 4096) = 0 4055 uname({sys="Linux", node="baby", ...}) = 0 4055 mmap2(0xf0dea000, 4096, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xad1ff000 4055 madvise(0xf0dea000, 4096, MADV_NORMAL) = -1 ENOMEM (Cannot allocate memory) 4055 munmap(0xad1ff000, 4096) = 0 4055 uname({sys="Linux", node="baby", ...}) = 0 I wonder if it could be trying to do some fancy memory operation that only works on PAE kernels.
The problematic site use some invisible java. After removing icedtea-web the site complained about missing functionality but did apparently no longer crash. It seems like removing ~/.icedtea made the problem go away.
