Previously this year I install SME Server 7.1 on our server. It ran perfectly for the rest of the year, but just recently I started experiencing problems.
everytime the server is on line no one gets on the internet, it takes too long and times out. thinking that the automatic updates was causing the problem i disabled it and only enabled it during the night, so that it would update during the night and not interfere during the day. this did nothing to solve the problem!
in a desperate quest to find a solution i downloaded (the only way to get on line was to shut down the server) and installed SME Server 7.2. this did solve our problem a little, i could get on line but it's ssoooooooo sloooooowwww and at times it takes too long and times out also.
in desperate need of assitance

The last time I saw this (here in the forums) it turned out to be the result of an infected workstation on the network.
I've seen this sort of behavior (on non-SME networks) with older peer-to-peer file sharing packages.
Do you have more than one workstation behind the SME? What happens when you disconnect all of them but one?
Is the SME acting busy (unexpected disk activity)?
Do you have any P2P or BitTorrent clients loaded (on workstations or on the SME)?
Do you have snort installed on your SME? (There was a problem with how snort handled log files that would cause severe disk thrashing)
Do you have SME7Admin installed? (There was an update around the time that SME 7.1.3 was released that had to do with server overload)

If you suspect the traffic clogged caused by SME (or any local workstation).
try iptraf tool
#iptraf
it will show where the packets coming from and where it goes.

Hi
I had the same problem about 2 months ago, my Server was using about 1GB of bandwidth a day!!!, and all the Workstation sin our small office were off.
I never did find the problem, as I just put our ADSL line straight into the router and not into the SME Server and it stopped.
The only thing that I did have enabled that may have caused it was fetchmail, and it was collecting mail form multiple Yahoo accounts.

"top" and "iptraf" should tell what's happen and where it goes.

Another thing that kills SME's are outgoing large e-mails ... cause SME tries to send it out fast so it uses all the bandwidth in turn it kills all incoming traffic or slows it down to a snails pace.

Does Wordershaper work on a semserver in 'server only' mode?
