Hi all,
I'm having some problems with FreeBSD 3.4-STABLE, and I was hoping
somebody could help me. The machine has had the same amount of
memory (32Mb), and the same kernel installed since April 4th, but in that
time it has reported many different memory sizes:
Apr 4 13:21:39 kenny /kernel: real memory = 16842752 (16448K bytes)
May 15 23:40:32 kenny /kernel: real memory = 31457280 (30720K bytes)
May 18 06:23:30 kenny /kernel: real memory = 20316160 (19840K bytes)
May 18 13:02:25 kenny /kernel: real memory = 17104896 (16704K bytes)
May 18 13:16:12 kenny /kernel: real memory = 17203200 (16800K bytes)
May 18 19:53:19 kenny /kernel: real memory = 16875520 (16480K bytes)
May 18 19:57:40 kenny /kernel: real memory = 16842752 (16448K bytes)
Jun 4 00:36:42 kenny /kernel: real memory = 16842752 (16448K bytes)
Jun 9 09:18:47 kenny /kernel: real memory = 31457280 (30720K bytes)
Jun 11 12:58:15 kenny /kernel: real memory = 21561344 (21056K bytes)
Jun 11 20:50:25 kenny /kernel: real memory = 16908288 (16512K bytes)
Jun 29 13:55:16 kenny /kernel: real memory = 31457280 (30720K bytes)
Jun 29 13:58:44 kenny /kernel: real memory = 31457280 (30720K bytes)
Jul 1 14:23:26 kenny /kernel: real memory = 16842752 (16448K bytes)
Sep 20 17:22:07 kenny /kernel: real memory = 16842752 (16448K bytes)
Sep 21 09:33:26 kenny /kernel: real memory = 16842752 (16448K bytes)
Sep 21 10:10:04 kenny /kernel: real memory = 16842752 (16448K bytes)
The machine is running very slowly right now, and constantly swapping,
with a 16Mb squid process in memory. The "active" memory shown by
"top" never goes over 8216K. I believe this is because it has only
detected 16 Mb of memory, but I have no idea why. I looked into forcing
the kernel's memory detection in the kernel config file, but without
success so far. If anyone can help me, I would really appreciate it.

Thank you kindly for any help you can give me =)
Cheers, Chris.
