Hi=20 I'm Sagara Wijetunga from Tomahawk Computers from Singapore, makers of th= e=20 Tomahawk Desktop, a FreeBSD based desktop operating system=20 (http://www.tomahawkcomputers.com/) which is free for personal use.=20 Ever since we upgraded our Tomahawk Core OS to the FreeBSD 7.2 sources, w= e=20 experienced a strange issue as follows:=20 1. The root cannot login from the console, child process forked die wi= th=20 =E2=80=9Cuid 0: exited on signal 11=E2=80=9D. 2. Normal users can log in, no issue. 3. Normal users can type =E2=80=9Csu=E2=80=9D and become root, but =E2= =80=9Csu -l=E2=80=9D=20 results child process forked die with =E2=80=9Cuid 0: exited on signal 11= =E2=80=9D. 4. The /var/log/messages shows =E2=80=9C(cron), uid 0: exited on signa= l 11=20 (core dumped)=E2=80=9D=20 We use a different build method to create Tomahawk Core OS, therefore, we=20 earlier decided not to complain about this issue till we release the beta=20 version as we were thinking without having access to our OS it may be=20 difficult to diagnose this issue.=20 Then we saw =E2=80=9CDeadlock in a multi-threaded program during fork(2)=E2= =80=9D on=20 FreeBSD website and upgraded our sources to the latest and rebuilt the=20 Tomahawk Core OS but the problem we face did not go away.=20 Appreciate if the FreeBSD community could give us a helping hand to ident= ify=20 the cause of the issue we are facing.=20 Kind regards Sagara Wijetunga
