Hi there,

Got a q.

It came to my attention that the traffic on one of my boxes has dropped signficantly twice during the last day, while my first thought was a problem with another box (which holds the main site and the box in question is a file server), but it was fine.
Then I've noticed a massive spike in open TCP connections, but I have no idea what could be a reason.

here are the graphs:

the system is p4 2.8 HT, 1.5 gigs ram, 2xIDE 7200 RPM, 100 mbit connection. OS - RedHat9. webserver - thttpd (it could be a reason for the prob).

Thanks!

One possibility is if you are hosting documents, some web or search engine spider opened a large number of connections to your servers to index them. This use of available connections resulted in decreased traffic overall because each connection could be retrieving data at a slower rate.

Of course, this is only one possibility and the information you provided would not be enough to determine the exact cause. Perhaps logs would be helpful if they are being kept.

that's possible. i'll enable to check it later if it will happen again (right now i've sheduled it to process & clean 'em hourly (the log is growing pretty fast, around 50Mb/hr)).

thanks for the idea, dside443!
