I have a dedicated line customer who is having some problems and I thought I'd throw it on the table here to see if it sounds familiar to anyone else. I am running user PPP for this customer and he is connecting his Windows 95 machine running the Micro$oft Personal Web Server. He connects fine but after some indeterminate period of time, anywhere from 6-8 hours to a week, his server becomes very slow. When he's up and running normally, ping times are around 200ms (31.2k modem connection, on average) but when this condition starts, delays can be up to 9 seconds. Actually, what happens is that if you ping him, there will be no replies at all for around 8 seconds, then all of the accumulated pings are returned at once (in sequence), so you see ping times of 8,7,6,5,4,3,2 and 1 second and then the whole pause/return sequence repeats. When you actually try to download his web contents, you get a long initial delay, then a couple of hundred bytes transfer and another long wait (10-20 seconds), then a little more and so on. The modem is external, so when I ping him, I do see the outbound activity in sync with the stdout, so I have pretty much ruled out a problem on this end with PPP. It looks to me like his W95 box runs some application that produces a serious memory leak, forcing it to start swapping more and more, but I can't confirm that. When the user reboots and reconnects, everything is back to normal until the next time. My only "fix" for him is to run a cron job that pings him every 15 minutes and then email him when I see the response times go up. Anybody else seen this sort of behavior?
