Since then it=E2=80=99s started hanging every few = days. Today I happened to have a =E2=80=9Ctop=E2=80=9D instance running on the = serial console. The system is minimally responsive to the network (ICMP = and CARP are working, but no services). =46rom the top output it=E2=80=99s not clear what resource it=E2=80=99s = out of. There=E2=80=99s no swap configured, but that what it looks like = it=E2=80=99s trying to do?=20 The =E2=80=98pf purge=E2=80=99 process is suspicious. There are no pf = rules configured on the system (it should be all disabled). Any suggestions? (Other than =E2=80=9Cseriously =E2=80=A6 64MB = memory?!=E2=80=9D).
