It freezes hard. I *think* it freezes<BR>hard b/c I haven't tested pinging it when it's down. But it doens't<BR>reply to anything including ctrl-alt-bkspace, or ctrl-alt-f1. And I<BR>know the /var/log/messages file stops creating --MARK--  entries<BR>during this time. When I find it frozen, there is video, but no<BR>response to mouse or keyboard.<BR><BR>In our tests, we only experimented with 1 client. Could 5 clients<BR>create too much demand on our server? I recently installed the ssl<BR>update and rebuilt the images...could I have done something wrong<BR>there? And one more detail: we're posting our username-password info<BR>per computer...it's conceivable that one user might be getting signed<BR>in more than once. Would that do it? Or how about using Adobe Flash 9?<BR><BR>thx so much,<BR>-peter<BR>Bard High School Early College<BR>NY, NY<BR><BR>-- <BR>edubuntu-users mailing list<BR>edubuntu-users@lists.ubuntu.com<BR>Modify settings or unsubscribe at: <A href="https://lists.ubuntu.com/mailman/listinfo/edubuntu">https://lists.ubuntu.com/mailman/listinfo/edubuntu</A>-users<BR></DIV></BODY></HTML>
