[R-sig-dyn-mod] memory issues with lsoda

Hi,
When trying desolve with lsoda, I often get an error saying that I use
lots of memory, e.g.
Error in lsoda(y, times, func, parms, ...) : cannot allocate memory
block of size 134217728 Tb
In addition: Warning message: In lsoda(y, times, func, parms, ...) :NAs
introduced by coercion to integer range
With a different solver (e.g. ode45), I don't get this problem. What is
different in these methods that they use the memory so differently, and
can the lsoda error somehow be fixed?
Cheers,
Rampal
