Bite bullet, add more physical memory.
For a time-critical process.... that seems like it is business critical, then do the right
business decision. Purchase more memory to get the job done.

Subject: Howto avoid a process beeing paged out?
Hi,
I run a time-critical application on a vServer which seems to have very little memory
(even 512mb are guaranteed).
Every page that hasn't been accessed the last few minutes is immediatly swapped out,
and if a request comes in the system is busy many seconds loading the working-set of the
application into memory again.
Is there any way to prevent applications from beeing swapped out?
I tried to call mlock(), but after this call dynamically loading shared libraries failed
:/
Thanks, Clemens
