I setup Gentoo on my Thinkpad 770 that I just got. I'm using distcc to do most of the compiling on my desktop machine (Athlon 1.3GHz w/768MB RAM). I'm running the same version of GCC, binutils, etc. on both machines. Most compiles work just fine. Every once in a while (12 times in one day during bootstrap and emerge system) the compile will just hang on the laptop. It looks like the compile finished on the desktop (no cc or gcc processes running) and was sent back to the laptop, but the desktop didn't send the DONE signal. The network connection remains open, so the laptop sits there and waits indefinately for the DONE signal. If I run '/etc/init.d/distccd restart' on the desktop, it breaks the network connection and I get an error on the laptop that the file descriptor (socket) was unexpectedly closed before it got the DONE token from the desktop. It then proceeds to compile locally. I was able to hack my around this by opening an xterm on the desktop and running 'while `sleep 30`; do /etc/init.d/distccd restart; done', but this is very definately a nasty hack and it will restart distcc in the middle of compiles.
Additional info: I had originally thought the problem was because of the PCMCIA NIC I was using, but the problems persist with my wireless NIC. It did it during the install with the LiveCD's 2.4 kernel and now with my 2.6.4 kernel. Is there any additional information I can give to aid in tracking down this problem?
Follow the relevent bullets on this document and paste the results. http://distcc.samba.org/problems.html Include what kernel and NIC modules you're using on each system.
Laptop: gcc 3.3.3 one NIC used the SMC PCMCIA something or other driver and my current one uses the madwifi driver distcc 2.13 Desktop: dmfe driver for NIC gcc 3.3.3 distcc 2.13 I can't duplicate the error message right now, since I'm in the middle of a Mozilla build that's taken over 24 hours already (233MHz processor).
Are you able to duplicate the error now?
Could you post emerge info for both boxes? Tried changing network cables (or nics in the desktop)?

I'm trying to reproduce the problem now to get some actual output. It doesn't always do it. I saw something else that worried me. I ping'ed by desktop machine from the laptop (w/ wireless NIC). The first 7 packets were lost and everything after that got a response. 'ifconfig ath0' on the laptop didn't show any packet errors or collisions. I'd want to lean towards a driver problem with the card, but it did it with my wired PCMCIA NIC also.
I just checked all my boxes here, none of them have any collisions (even the server that's public IP is exposed to my isp that gives off horrible traffic). You should probably try tracking down what's causing those (google should be a good thing to check for that).
The common piece of hardware is my Speedstream DSL modem/router. I can't really replace that. Although, it is a few years old and runs at full bandwidth about 24/7.
I've tried to replicate this bug again. I see it happening, but it's not giving the error anymore when I do '/etc/init.d/distcc restart' on my desktop. The compile on the laptop is still stalling, though.
is this still happening?
I haven't compiled anything on my laptop since my last comment. I can give it another go in the next few days, but the problem is intermittent.
