Well, it can sound wierd, but the bottom line is that the malloc failed
because there was no 64K block of memory available at that instant.
Doing a show mem after the failure, and then after rebooting and running
a while would show how much memory you typically have available. Looking
at the show mem detail (and check show mem dead) will give you an idea
of the usage distribution and maybe where it's all gone.
It could be a bug or memory leak, it could be something that you didn't
realize the impact of invoking. We have serveral 128K routers in our
network running 12.0.*S. Some of them are as happy as clams, others
need to be upgraded to 192 or 256M to make them long term stable.
