Hi,

Has anyone modified their Swap partition?  I have been working through restart issues and, while I have cleaned up the majority by limiting the number of devices I still see random restarts with out of memory errors.

I have noticed the Swap partition is less than the installed memory:

pi@Firewalla:~ (Firewalla) $ free -h

              total        used        free      shared  buff/cache   available

Mem:           994M        780M        105M        5.0M        108M        111M

Swap:          621M        275M        345M

The general consensus for linux with less than 2G is memory is a Swap that is twice the installed memory.  I am thinking of bumping it up and wondering:

1. Has anyone tried this?

2. If so, any challenges or learnings?

Thanks.

  The swap you see is not the typical swap to disk "swap". 

  Since this is an embedded platform, you shouldn't swap to disk, it may significantly reduce your performance. A better way to deal with the problem is to look at the devices and reduce the load (such as p2p or p2p like flows), and I assume this is exactly what you are doing.
