[Linux-ha-dev] ipfail: high CPU utilization

[David Abdemoulaie]

I've had a few issues with ipfail mysteriously utilizing 100% of the CPU
for very long periods of time.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
27688 hacluste  25   0  2308  992  796 R   99  0.0   5663:27 ipfail

strace shows a deluge of the following:

poll([{fd=4, events=POLLIN|POLLPRI, revents=POLLIN|POLLHUP}, {fd=5,
events=POLLIN}], 2, 0) = 1
gettimeofday({1179763006, 668872}, NULL) = 0
poll([{fd=4, events=POLLIN|POLLPRI, revents=POLLIN|POLLHUP}, {fd=5,
events=POLLIN}], 2, 0) = 1
gettimeofday({1179763006, 669083}, NULL) = 0
poll([{fd=4, events=POLLIN|POLLPRI, revents=POLLIN|POLLHUP}, {fd=5,
events=POLLIN}], 2, 0) = 1
gettimeofday({1179763006, 669293}, NULL) = 0
poll([{fd=4, events=POLLIN|POLLPRI, revents=POLLIN|POLLHUP}, {fd=5,
events=POLLIN}], 2, 0) = 1
gettimeofday({1179763006, 669501}, NULL) = 0

Any ideas? Should I just kill this process?

My version is:

heartbeat-1.2.3.cvs.20050927-1.centos4

running on Centos 4.4

Linux <hostname removed> 2.6.9-42.0.3.ELsmp #1 SMP Fri Oct 6 06:21:39

Thanks!
