nova client hangs for aprox 25 seconds before completing

[James Luhrsen]

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

s# netstat -nxp | egrep 972315

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

Any other ideas for debugging this?

Thanks,
