Comment 1 for bug 1774431

Description of problem:

The quota daemon, rpc.rquotad consumes 100% CPU on one core.
It does answer correctly to queries though.

Version-Release number of selected component (if applicable):

quota-rpc-4.04-5.fc28.x86_64

How reproducible:

100% and immediately.

Steps to Reproduce:
1. dnf install quota-rpc
2. systemctl start rpc-rquotad.services
3. top

Actual results:

You see 90+% CPU usage from rpc.rquotad

Expected results:

Minimal CPU usage from rpc.rquotad

Additional info:

1) Downgrade to the last version of Fedora 27, quota-rpc-4.03-9.fc27.x86_64
   makes everything okay again.

   dnf -y downgrade quota-rpc --releasever=27

2) strace on the daemon spits out endless repeats of:

poll([{fd=4, events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}, {fd=5,
  events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}, {fd=6,
  events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}, {fd=7,
  events=POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND}], 4, -1) = 2 ([{fd=5,
  revents=POLLHUP}, {fd=7, revents=POLLHUP}])
accept(5, 0x7ffe61698700, [128]) = -1 EINVAL (Invalid argument)
accept(7, 0x7ffe61698700, [128]) = -1 EINVAL (Invalid argument)
