Hi,
The version output by the ipvsadm command is: IP Virtual Server version
0.9.7 (size=65536)
(Also the RedHat version is 7.3 not 7.2 (typing mistake in previous email))
The software is in production and is running well, handling a lot of
traffic. But we have had 2 crashes in about 3 weeks.
Thanks,

Hello,
Which version of ipvs are you using? Have you tried ipvs-1.0.6 for kernel
2.4?
Regards,
Wensong
