[Bug 1210297] [NEW] nova client hangs for aprox 25 seconds before completing

[James Luhrsen]

Public bug reported:

Looks like this forum is not well used, but not sure where else to ask
this.

When I run the nova client I see that it hangs for 25 seconds or so before returning.  This is as
a specific non-root user.  With root (or sudo) this delay/hang is not there and it's not happening
for other users either. 

This is without any options (e.g. "nova help").  Using "strace" I see that it's timing out on some
filedescriptor after 25 seconds.

17687 1375377962.257688 poll([{fd=6, events=POLLIN}], 1, 25000) = 0
(Timeout) <25.025049>

That file descriptor is a socket with an endpoint pointing to python, but thats as far as I have
gotten:

# ps -elf | egrep nova
0 T jamo     19040  8910  3  80   0 - 23150 signal 11:10 pts/28   00:00:00 /usr/bin/python /usr/bin/nova
0 S root     19046  8876  0  80   0 -  3406 pipe_w 11:10 pts/7    00:00:00 egrep --color=auto nova

unix  3      [ ]         STREAM     CONNECTED     972315   19040/python


I must have something wrong with this specific users environment, but I can't figure it out.

Any other ideas for debugging this?

Thanks,
