[Samba] (no subject)

    Is there a known bug that samba has on older machines in low memory environments? I have set up a 486 with 24Mb of memory with RedHat 7.1. I set it up to run dhcpd, xinetd, and samba. Samba was not run through xinetd. The samba server had a tendency to crash the machine if a large upload was sent to it. Occasionally, it wouldn't crash, but windows would error and stop uploading. No problems were ever experienced while downloading from samba. As RH 7.1 used an old version of samba (2.0.xxx), I upgraded to the latest available. I also tried it with a newer kernel and various custom kernels. I still got the same result: samba crashing the machine on heavy uploads. I later tried using 3com's own driver for my NIC card, as I thought the kernel's included 3com vortex driver might be at fault. This did not help.
    Recently, I installed an LFS system, book 3.1, and put up dhcp, xinetd, and samba version 2.2.3a. After getting everything working, I got the same behavior: system crash on a large upload. This is with a completely independant install, LFS instead of RH, and I am still getting this error.
    My guesses are that maybe samba doesn't like the extreme low mem conditions on my box; it uses almost all physical memory at idle, but there is plentiful swap.
Maybe this is being caused by the drives being too slow, possibly coupled with the fact that there is heavy swapping. (The old motherboard doesn't do DMA IDE).
Maybe this is a misconfigured samba.
Maybe this is not a samba problem. (Although I did do limited use of FTP under RH and never had a problem).
    I would appreciate any way to narrow down what this might be or any other ideas what it might be. I've seen another reference in the archives in 2000 of a guy that had a machine that timed out alot, but nothing about his server crashing. There was no news of how or if it was resolved though. I'd really like this 486 a samba server. Am I asking too much from old hardware?
