Initially, everything works. However, after a few hours (4 to 5) users start complaining about slow connection speeds, and eventually they are not able to connect to the Exchange server, or network drives shared over the WAN at all. If I put the FreeBSD 4.8 server and mpd 3.17 back on line, everything will start working properly almost immediately. To me, it sounds like a memory leak, or the operating system is running out of stack space. My network is configured in a star configuration. 5 offices connect to the corporate network using an mpd to mpd configuration. The corporate office has a dedicated T-1 and the other offices all have DSL connections. Nothing out of the ordinary is showing up in the mpd logs. And, nothing out of the ordinary is showing up in the syslog. In my mpd.conf file, I have 34 pptp connections defined, and at most 10 are in use at one time. The server is a Celeron processor with 128 MB of RAM. And, during peak usage times, I am showing approximately 1% usage on the processor. If needed, I would be happy to post my configuration files and log files. I have checked the log files around the times users report problems, and do not see anything out of the ordinary (no dropped connections, new connections, missed replies, etc). And, checking the T-1 usage at the time, approximately 500K of a full T-1 was in use. Any suggestions would be greatly appreciated. Thanks in advance. Jay
