[Xen-users] gettimeofday and endless looping

["John Wells" <jb@xxxxxxxxxxxxxxxxxxxxx>]

Guys,

We're having a similar problem to that documented, but not resolved, here:
http://lists.xensource.com/archives/html/xen-users/2005-08/msg00110.html

The python process that runs "/usr/sbin/xend start" has reached 99.9% CPU
utilization.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 3569 root      25   0 12952 7876 2456 R 99.9  6.2  13444:26 python
/usr/sbin/xend start

xm commands don't respond, because the daemon process has apparently
entered an endless loop. Stracing to the process yields:

gettimeofday({1132076987, 801316}, NULL) = 0
gettimeofday({1132076987, 801401}, NULL) = 0
gettimeofday({1132076987, 801486}, NULL) = 0
gettimeofday({1132076987, 801571}, NULL) = 0
gettimeofday({1132076987, 801657}, NULL) = 0
gettimeofday({1132076987, 801742}, NULL) = 0
gettimeofday({1132076987, 801828}, NULL) = 0
gettimeofday({1132076987, 801913}, NULL) = 0
gettimeofday({1132076987, 801999}, NULL) = 0
gettimeofday({1132076987, 802084}, NULL) = 0
...over, and over, and over again.

This is on a CentOS4 (RHEL4) box, on an i686.
Kernel: 2.6.11.12-xen0
Xen version: 2.0.7

Has anyone else experienced this? Any idea what might be causing it?

Thanks!

John
