I have a machine with 32 bit Linux 2.6.22-15 (Ubuntu Gutsy) that is installed on a 8 GB server with two quad core CPU.

The problem is that it slowly runs out of LOWMEM.

Every minute it loses approximately 400 KB of LOWMEM, as evidenced by

grep LowFree /proc/meminfo

This seems to be fairly constant throughout the day. During the day the machine really took a beating and performed admirably, moving approximately 70 megabits of data per second on average. It was also busy computing stuff. However, the rate of low memory decline did not seem to depend on how busy the machine was.

Here's the printout of lowmem throughout the day starting at 6:40am.
