This is probably unrelated, but I experienced a similar issue recently.
In my case it was because I was attempting to do some IDL processing on
a frontend (or login) node of the supacomputer I was using. That is
(somehow) restricted by the system setup. I'm guessing everything was
working fine until I passed some memory usage limit or there were too
many other folks on the login node - I was not doing anything too
complicated or big.
When I started an interactive job on a compute node the 'Unable to
allocate memory' error went away. (Aside: The sysdocs said to run IDL, a
whole node should be taken! I guess memory management is an issue in
general with IDL.)
So, if the OP is using IDL on a shared system (s/he did say "server"
so...other users?) maybe the other users are requesting enough resources
to make the OP's script run out of available memory in a seemingly
random way?
(I'm waving my hands about in the air trying to make the scenario seem
reasonable :o)
cheers,
paulv
