Have you checked dial-on-demand?
Any entries in the system log?

Please can you provide the output of commands:
ifconfig
ps -ax | grep mpd5

dial on demand is checked but in older snaps, on clicking disconnect, pppoe used to disconnect and due to dial on demand it used to again attempt connection but currently no entries in system log nor any attempt to disconnect or reconnect.

one step i do to get over this is as follow:

on clickign disconnect nothing happens even after a few mins so i go to system > routing and in the list it shows the GW_WAN so i simply click edit and press apply without changing anything and then a reconenct is attepted and system log shows below stuff

works fine now

upgraded from 22nd july nanobsd to 31st july nanobsd and disconnect button is broken again, might not be disconnect button but recent changes to pppoe or itnerface caused it, now when alix boots, pppoe connects fine on boot but suppose if there is a disconenct from isp or u pull the cable out or u click the disconnect button, the connection is not brought up again and there is a endless loop of the below warnings causing the webgui to be unusable.

happens even if u got to wan under interfaces and make some changes or simply click save and then apply it and that would be the end of the wan connection till alix is rebooted

Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70
Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70
Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70

on further investigation, the wan interface page, period reset and dial on demand all r affected

i tried to trace the changes between 22nd july to 31st july but wasnt able to find whats causing this pppoe reconenct issue due to pppoe_wan.pid file not being found but the file exists and contents r also fine.

could some1 fix this so i can try latest snaps to provide feedback on other issues?

to further narrow this down, i upgraded to the 30th july snap (pfSense-2.0-BETA4-1g-20100730-1433-nanobsd-upgrade.img.gz) and after the first reboot, i went to interfaces and clicked disconnect and only once i got the same warning
Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70
then i got a php warning like output headers sent before .....

then i rebooted the alix again and after that now when i press disconnect, those messages dont appear and works as intended and the first time with the messages also, it went on with the disconnect and reconnect procedure compared to the 31st snap which just goes in the loop of trying to reconnect but making everything unusable.

all snaps from 31st july to 5th august keep giving this in browser in a endless loop when disconnect button is pressed

Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70

Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70

pppoe is disconnected but then never connected

all snaps from 31st july to 5th august keep giving this in browser in a endless loop when disconnect button is pressed

Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70

pppoe is disconnected but then never connected

still the same with the 7th august snap, if some1 could fix this minor issue, just caused by some php warning

still not solved, as a matter of fact its gone more worse. Now either if u got to the wan interface page and click save and apply or go to interfaces under status and click disconnect, what actually happens is, the pppoe is disconnected but now due to the patch, the php warning doesnt come but complete webgui freezes and pfsense becomes unusable untill a reboot and there is no way to know also what error occurred.

Can i have your config and the system logs after the webgui freezes?

after clicking disconnect, below r the details of system log and ppp log

i got so frustrated with this issue that i did a clean install on another CF card and reconfigured it from scratch and tried it and i got the below message once and same freeze of the webgui
Warning: file_get_contents(/var/run/pppoe_wan.pid): failed to open stream: No such file or directory in /etc/inc/util.inc on line 70
this mde me doubt if the last patch was there in the latest snap and rebooted alix and checked and it seems to have the patch so no clue whats causing the php warning, what i think is some other process or so is locking the pppoe_wan.pid file which exists and consists the pid of mpd and due to the locking, the php scipt is unable to access it and so the above php warning and so the pppoe is never brought up again.

any1 else having this issue?

im on the latest snap and still issues with this, further testing results below:

1) on reboot pppoe conencts fine.

2) if u go to interfaces->wan then click asave and apply then conenction brought down but never gets up till php timeout occurs after which only the webgui is usable again, system log and ppp log dont show anything after mpd process termination so no idea what goes on.

3) if u go to interfaces->wan->advanced and mlpp and then click save then conenction is brough down and up successfully.

4) if u go to status->interfaces and click disconenct then pppoe is disconnected but never got up again and webgui is only usable after php timeout occurs then going to same and clicking conenct enver gets the connection up.

in all cases dial on demand is enabled but disabling also doesnt change any of the above scenarios. last working snap was of 30th august.

there is some correction

all above scenario work fine if dial on demand is disabled and dont work if its enabled.

Latest snapshot should be ok, i found where the loop was occuring.

now atleast with dial on demand ticked, the pppoe is disconnected and reconnected and receives new ip from isp but the webgui has some issue coz as soon as disconnect is pressed, the page just keeps showing loading and never ends, its suppsoed to return to interface page and even if u goto interfaces->wan and make some changes and click save and then apply, then also page keeps showing loading but never ends, in the abckend the pppoe is brought down and up again sccessfully, so in this case then browsers stop button needs to be pressed then only the webgui is reusable,

The GUI should respond now properly with the latest snapshot.

im on the 21st snap and still after clicking disconnect, the page just keeps showing loading whereas the pppoe is already brought down and up again.

seems to work fine on the latest snap.
