Unless you are comfortable delving into the C code and working on these issues, uClinux will probably never be an appropriate system for you with which to run Asterisk. Apparently, that version of Asterisk originally comes from the OpenWrt world, and includes a bunch of patches applied to the Asterisk source code before compiling it into a package. Since it's part of the official firmware provided by the manufacturer, I guess it's been reworked to run OK in that restricted environment. I do, intend, though, to find some kind of watchdog to monitor processes and memory, and restart them if necessary.
