I have a Google account that I keep permanently logged in on two computers + an android phone.
On one of them I get signed out every one or two days, while on the other I'm signed in all the time (unless I log in or the cookie expires – once a month or so).
I've checked the account activity (the bottom link in Gmail) and there are no signs of weird account activity; it's got traffic just from these two IPs and my mobile.
Has anyone else experienced weird log-offs like these? Is there any particular reason why it may behave like this?
Update
I just noticed this: while I'm experiencing the logout of iGoogle in my Chrome browser, I can go to Gmail (by entering the address in the address bar) and I'm logged in.

I use Chrome and iPhone 4 and haven't had this problem. Well, maybe once I think. But nothing annoying. If your settings in your browser is correct. And you have selected the remember me setting for your google account. The only thing I've found in researching the issue is to go to this link
"http://www.gmail.com/gmail&service=mail&[email address]&Passwd=YOURPASSWORD&null=Sign+in
I got this from this chat room with a slew full of people having the same issue as you.

I'll try to figure something else if it doesn't work. Or someone else can hopefully answer.
