sysctl VM settings spontaneously return to their default values

I am pretty clueless about this issue.

In my workstation's /etc/sysctl.conf I have the following variables:

vm.dirty_writeback_centisecs = 1500
vm.laptop_mode = 5

which are set correctly (according to /proc/sys/vm/* files) on boot. However, after some uptime (usually several days) and moderate swap activity the above settings return to their defaults, namely 500 and 0. I have to login as root and run sysctl -p, but later the situation repeats itself...

Any ideas as to why this happens are greatly appreciated.
