Description Alan Coopersmith 2004-04-25 08:21:53 UTC
[Originally reported to Sun as Sun bug id #5025208, which is fixed in Solaris 10.]

A user writes:

I have a large number of entries in the .Xauthority file ...

xauth list | wc -l

If I execute:

    xauth list | head

I get, as expected, the first 10. If I repeat the command I get ...

xauth list | head
xauth:  error in locking authority file .Xauthority

Sometime the failure doesn't happen (presumably because Xauth has removed the lock
before the SIGPIPE is delivered).

I confirmed this with my large .Xauthority and found the fix was simple - add
SIGPIPE to the list of signals that xauth catches with a routine to unlock the
.Xauthority file.
