Hello,
About a month ago I posted a question to the list about
ping being broken the second time you ran it. The
problem seemed to be related to the shell I was using
(msh). I was finally able to get back to this problem
and find a fix.
Earlier this year a message was posted to the busybox
mailing list that solved the problem:
http://www.busybox.net/lists/busybox/2008-February/030260.html
After integrating this patch, I have been able to run
ping without any failures.
Attached is a reformatted patch.
Best regards,
Matt
ps. - I noticed this patch hasn't been accepted into the
busybox base, but saving the signal state does seem like
a good idea.
