Kernel 1.2.13: Files > 2MB via POP3 Brings Mail-Hub to its Knees

Kernel 1.2.13: Files > 2MB via POP3 Brings Mail-Hub to its Knees

Post by tajud.. » Sat, 28 Mar 1998 04:00:00



Hi,  I've got a Linux 1.2.13 system on a 10baseT ethernet network. On
the same network is a router w/T1 DS-1 access to the Internet.  I've
got the box setup as a mail-hub via Sendmail.  Users retrieve their
e-mail from the hub via POP3.  Whenever a user's spool exceeds 2MBs
and that user initiates a POP3 retrieval of that spool, the system's
performance suffers BIG TIME.  What's happening here?  How can I
remedy this?  How do I check the status of the swap partition?  Also,
I read somewhere that if I wanted to add more RAM to the system, I
would also have to add more SRAM (L2 cache).  I can't add more SRAM on
this particular Compaq box.  How about if I just get the RAM, say
256MBs, the re-install the kernel.  Should I upgrade to 2.0.33?   Lots
of questions I know, but I'd greatly appreciate any insights.

I would upgrade your system considerably - but that's just me. A newer
pop3d, certainly (try the IMAP daemon, which covers pop2 and pop3 as well
as IMAP proper) but also the newer kernels have smaller memory
requirements and, I believe, newer networking code.

But, yes, upgrade. Everything you can. 1.2.13 is pretty far back there.

1. strange problems 1.2.13 --> 2.0.0 --> 1.2.13

Hi,

I have some strange problems with the new kernel source tree...

after the installation of the new sysvinit-2.62 the linux-2.0.0 kernel
complains sh:/bin/bash cannot execute...
with 1.99.7 this works fine
and at least I'm totally unable to recompile the 1.2.13 source tree due
some strange asm errors in main occurring in asm/io.h referenced by
bugs.h  (also within the asm tree). Of course I checked the appropriate
links to for the linux source tree /usr/include/linux
                                                asm

Please help....
