Package: screen
Version: 4.0.3-11+lenny1
Severity: normal
sometimes when using "screen -x" to re-attach to an existing session,
the process will appear to hang and never fully attach. this might
happen with "screen -r" as well, but I generally only use -x and
probably as a result have only seen the bug that way.
after a "screen -x" process has hung while attempting an attach, opening
another terminal and trying another "screen -x" appears to work fine and
does sucessfully attach to the session. but the hung process remains hung.
I don't think this is releated to #326571 because I have not been attaching
from within sessions when the hang has occured.
performing an strace on the hung process reveals this:
linear:/# strace -p18362
