Hi,
a gmail account that I have been using with no issues via imap has
started to misbehave and I have no clue why.

The error message being generated is as follows:

'Too many simultaneous connections. (Failure)'

followed by

'Login to server imap.gmail.com failed.'

Any ideas?

Have you seen their recommended settings page?

https://mail.google.com/support/bin/answer.py?answer=78892

Click on the 'Thunderbird 2.0' link.

Specifically, the 'additional steps' listed after step 5. Where they
show you how to change the 'mail.server.default.fetch_by_chunks' preference?

I'm thinking that would probably reduce the number of requests made to
the server, and may help alleviate the problem. Just a guess, though.

Hi Alex,
many thanks for the heads up regarding the TB tunning. Unfortunately
they did not make a difference.

I have 3 Gmail account referenced from TB. Two of them work with no
issues at all but this one account, since last week, refuses to play
ball!

Thanks in advance for any additional help.

There is no need to keep bumping this, it has not been up that long.

Have you tried the obvious step of removing the account and recreating it?

This issue has now been resolved!

It would seem that TB has an issue with the number of folders it like
you to have on an Gmail account. Simply deleting some of the more
redundant folders I had resolved the issue completely.

I presume that this is a bug as I never had an issue with the account
in question when I setup imap on Outlook 2003.

On the other hand, in looking through the GMail support groups, even
Outlook users are experiencing this error about "too many connections".
What is not clear, to me, is whether this is a client issue, or a
server issue. In other words, is the error that the client (TB or
Outlook) is *creating* too many connections, or is it that the the
server is *experiencing* too many connections, in total, from all users?

Postings on their groups seem to suggest that it is a server issue, as
it seems to be an intermittent error. Although I don't have an answer,
I'm just curious, do/did you get it *every time* you tried to connect?

For reference, the Gmail help groups are here:

I just started having this same problem in Apple Mail, so I assume
it's a server issue. Everything works fine for the first couple
minutes, but then I get the "Too many connections" error. I connect to
Gmail IMAP via my MacBook Pro and my iPhone only. Also, doesn't seem
to be any problem with accessing mail on my iPhone through the mail
client. So does anyone know for sure if this is a client issue or
Google's server issue? Anyone from Google tech support that can help
us out here?

Some thing related to this thread from a conversation with my ISP
support for a news server connections problem. On the client side Tb by
default sets two connections as the max for a server. My ISP outsourced
there news service [NSP] and leased only two connections between the
ISP and the news company. This causes many traffic jams at the ISP's
concentrator which is pulling news from the NSP. Result is lots of "Can
not connect" messages until some network techs got smart and programed
the servers to issue a "Server is too busy" when the connection had to
be rejected for lack of capacity. So a more detailed server responce is
possible than the dumber "Too many connections" default reply.

I'm experiencing the same "too many simultaneous connections" error
using Thunderbird on a gmail account.
I tried the recommended settings (https://mail.google.com/support/bin/
answer.py?answer=78892&topic=12920#), but
it did'nt solve the problem.

If I restart Thunderbird, the problem appears to go away for a few
hours, then it comes back.

I have one gmail account, with 10 IMAP folders. I haven't tried
eliminating some of the folders. I will if someone can confirm that's
the source of the problem.

I have outlook 2007 and am having the same problem. I am not
connecting with any other email client or on another computer. I do
have 13 folders, but they are all kind of important.

Filtering the Config Editor screen display for IMAP I found this preference:
mail.imap.max_cached_connections
The default value is 10

I do not know how IMAP works, but experience with NNTP suggests this may
be related to your comment. What has G-mail tech support said about how
there servers handle accounts with more than to mail boxes? Is each
mailbox considered a separate connection?

Good idea. I'll try tweaking it, although the problem seems to have
gone away
since I made the other tweaks.

G-mail tech support? How does one contact them? I haven't submitted
this problem.
