Apache crashes due to error log file size

Apache will crash if your error log or access log's file size reaches 2GB which is the maximum file size of Apache in Linux.

When this problem occurs, you can just delete that file and restart Apache.

You might also consider switching Apache log from normal log into zwrotatelog which will consume a bit more of your server's resource!

We cannot use the latest version of Mail For Exchange (current version is 2.9.158 S60 3.1 HS). The problem is that MfE will just keep being unable to connect to the Exchange server. This definitely is a bug.

As far as I know, the only working version for Nokia E71 is Mail For Exchange 2.7.0 S60 3.1 which you cannot get it from Nokia's official site anymore.

I did a lot of Googling until I found this working version which you can get it from here
