Hi,
I have an old Soekris system with 64MB memory that I upgraded from 10.3 to 11.1
recently. Since then it’s started hanging every few days.
Today I happened to have a “top” instance running on the serial console. The
system is minimally responsive to the network (ICMP and CARP are working, but
no services).
From the top output it’s not clear what resource it’s out of. There’s no swap
configured, but that what it looks like it’s trying to do?
The ‘pf purge’ process is suspicious. There are no pf rules configured on the
system (it should be all disabled).
Any suggestions? (Other than “seriously … 64MB memory?!”).
