This is 5.1-beta/i386 on an ALIX about five years old,
running as my home server.

Recently, processes started to die for reasons unknown, as in

pid 20260 (postgres): user write of 118784@0x28052000 at 159088 failed: 14
pid 1872 (cron): user write of 118784@0x2b1e3000 at 30224 failed: 14

14 is EFAULT as per sys/errno,h
- what can be causing it?

It usually happens under a stress (the machine is pretty scarse
on resources, so 'stress' can be accepting a batch of DNS queries).
For example, the postgres EFAULT above happened exactly when a batch
of emails arrived.

Is this a memory problem? My login.conf limits all classes
to datasize-cur=100M. Can this be a memory HW problem?
