GNUGK taking 25% CPU when idle

Hi All
  I have a question on what could be caus

We have GNUGK running in a very minimalistic setup - all it does is processes LRQ and responds with an LCF for a static registration - also have a few restrictions in terms of IP address binding (can provide config if needed). However wht I see is that the process takes up about 25% load even when doing nothing (no LRQ recd)

Gatekeeper(GNU) Version(2.3.0)

TOP:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

I ran an strace on the pid:

futex(0xe55410, FUTEX_WAKE_PRIVATE, 1)  = 1
futex(0xe5549c, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xe55498, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1
futex(0xe55470, FUTEX_WAKE_PRIVATE, 1)  = 1
select(30, [3 13 15 16 18 19 20 21 23 24 26 27 29], [], [], {1, 0}) = 0 (Timeout)
select(30, [3 13 15 16 18 19 20 21 23 24 26 27 29], [], [], {1, 0}) = 0 (Timeout)

futex(0x7f24e8000020, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
futex(0x7f24e8000020, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7f24e8000020, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable)
futex(0x7f24e8000020, FUTEX_WAKE_PRIVATE, 1) = 0
select(30, [3 13 15 16 18 19 20 21 23 24 26 27 29], [], [], {1, 0}) = 0 (Timeout)

Any ideas on what could be going on here?

Thanks
