 cool to fix this. It's 100% reproduceable, I tested with another fonera. A
 firmware compiled a half year ago or so hadn't this issue.

 Yes it's true, this is a bad workaround so today I investigate the problem
 a bit, my fonera is very heavily loaded

 {{{
 root at OpenWrt:~# free
               total         used         free       shared      buffers
   Mem:        13620        12868          752            0            0
  Swap:            0            0            0
 Total:        13620        12868          752
 }}}

 and original ipkg status file is big!!

 {{{
 -rw-r--r--    1 root     root         4297 Mar 14 11:36 status
 }}}

 so the problem is clear... There no more space to load ipkg internal
 structure from ipkg status file and this bring ipkg to fail before
 dowloading package:

 {{{
 xsystem: ERROR: fork failed before execution ....
 }}}

 I think that only "clean" solution is to remove uneedded package (this
 reduce ipkg status dimension file), unload unneeded modules, stopping
 unneeded service, clear tmp, setting up swap etc etc...
 I made a mistake?
