I have noticed this for a few days now... And yes I have forwarded my ports  (In fact, I don't have any to forward, I am not behind a router). Whenever I double click on (I'm using windows) the bitcoin client, it pops up and begins acquiring connections quite quickly, up to about 50 or 60 connections in less than a minute I would say. When I run bitcoin.exe -server from the command line, the GUI pops up like normal but it only ever reaches 10-15 connections maximum, even after waiting for an hour or two. Anybody else notice this? Anybody know why? Notes: Windows 7, 32 Bit |

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

Really shouldn't happen, I see no reason why. Have you tried just opening alternating ones repeatedly for a while to make sure its not a first/second time thing?

10-15 connections means your port is properly forwarded, and other clients can contact you.

The networking code is the same in either case, so it was almost certainly just a coincidence and you got unlucky with the peers you connected to running -server from the command line.

How often do you get the chance to work on a potentially world-changing project?

I seem to recall someone else mentioning this earlier and attributing it to Windows. I don't know much about Windows networking code, but is there some sort of adjustable limitation placed on services? My detached bitcoind process running under Linux currently has 114 connections. |

As gavin said, its the same code either way. My bet is the OP opened it once noticed quite a few connections, closed it, and opened bitcoin one last time with -server causing him to lose all the previous connections. Even after waiting a while, those connections didn't come back because the clients who did have his node in their known node list lost their connection they won't make a new one and others just didn't connect to him. |

Update: 3 full days later of running bitcoin.exe -server and I am only up to 43 connections. It climbs steadily... BUT, if I were to simply open bitcoin.exe by double clicking on it, without adding the -server command... I would be up to 50-60 connections within a matter of minutes. Something about this doesn't seem right. I am running Windows 7 Ultimate, 32 bit. |

Have you actually tried? Yes. I have tried. And I will try again right now to double check. Just now... my internet connection cut out for a few minutes... I plummeted from about 40 connections (after 3-4 days running bitcoin.exe -server non stop) down to ~10 connections, and hours later I am still only at 12 connections. Once again... I have shut down by bitcoin.exe -server and opened bitcoin.exe by double clicking on it... after just 20-30 seconds I am up to 20 connections - where as it has taken me hours to get up to 12 connections using bitcoin.exe -serverI assure you, I am not crazy! |

Hmmmm...just doesn't seem possible. They do run the exact same networking code. Has to be something circumstantial but I have no idea what it would be...oh well, unless you don't have the 8 outgoing, you are fine. |

Pretty much the same issue here. I launch bitcoin -server and I will jump to 120 connections. Within 2 minutes that has dropped to 60-70, in a few days to around 50 then after a week maybe 5.
This just happened tonight with it dropping to 5 so I restarted it, initial was 117 connections, dropped to 66 then bounced back up to mid 80's then 90's, all within 5 minutes. I am behind a firewall and I do have ports open on both that Firewall and Windows 7 firewall.
