ps and processes

Question...

I run a program that monitors if a process is still running. It works
for a while and then tells me that the process has died even though it's
still running. I know why, but I would like to solve it. Basically what
happens is that I grep for a line to match a certain pattern. eg.

root     29437  0.0  0.3  4356 3224 ?        S    Jun24   0:00 perl /usr/bin/swatch -c /root/.swatchrc some other params here...
root     29438  0.0  0.3  4344 3212 ?        S    Jun24   0:00 perl /usr/bin/swatch -c /root/.swatchrc.page some other params here...

I'm basically grepping for .swatchrc and .swatchrc.page (I'm monitoring
them seperately).

After a few days however, those processes get swapped out to memory and
I get the following:

root     29437  0.0  0.0  4356    0 ?        SW   Jun24   0:00 [perl]
root     29438  0.0  0.0  4344    0 ?        SW   Jun24   0:00 [perl]

The W meaning that it has no resident pages. I asume that it has swapped
it out of memory. As you can see, the parameters have gone and therefore
my script thinks that it is no longer running.

I guess my question is, can I stop it from swapping out or use a command
that will still give me the full list of parameters (or both).

TIA
