Hi,
If someone can give me even a clue, a reference or any idea this will be very helpful:
For each dnn version i'm preparing the Hebrew version.
I have to make some minor code change in the file container.vb (just adding property to the class).
Then i recomile dotnetnuke.dll assembly.

In every server, on multiple hosts, the logged in user "looses its session",
thats means every minute the user is transfered to login page.
thats happen on almost every operation.

Any idea how to track that problem?
What might cause this? I'm not expecting direct answers, any way or idea
to monitor that problem may be helpful.

Thanks.

Can you supply some more details i.e. version of dnn, framework etc, so we can determine your issue (ideally you should log this at the public issuetracker http://support.dotnetnuke.com/project/Project.aspx?PROJID=23

With regards to random logouts, I fixed 1 main cause of this that was exhibited by the 2.0 version of the framework (more @ http://support.dotnetnuke.com/issue/ViewIssue.aspx?p=1&id=3013), this fix is in the 3.3/4.3 (and the soon to be released 3.31/4.31 stabilisation release).

Another common reason for logouts is a breaking change that Microsoft introduced in asp.net 2.0, where persistent cookies get expired more quickly. I blogged about this @ http://dotnetnuke.com/Community/Blogs/tabid/825/EntryID/233/Default.aspx , if this is the case, increase the timeout in your web.config.
