I'm running 2.6.20.21 as part of AstLinux 0.50 on a Soekris net5501
(it's a lower power Geode LX 433), and I occasionally have the box go
catatonic and have to be rebooted. Before that happens, dmesg fills up
with:
Feb 19 00:46:22 pbx user.warn kernel: printk: 12 messages suppressed.
Feb 19 00:46:22 pbx user.warn kernel: dst cache overflow
Feb 19 00:46:28 pbx user.warn kernel: printk: 18 messages suppressed.

Feb 19 00:46:38 pbx user.warn kernel: printk: 16 messages suppressed.
Feb 19 00:46:38 pbx user.warn kernel: dst cache overflow

I'll try to get the contents of /proc/meminfo next time before I reboot
(via the console).
What's going on? I googled for this message and got a lot of hits, but
nothing that seems specific to this issue.
What do I need to capture to get my smoking gun?
Thanks,
-Philip
