请问如何理解与确认“kernel is compiled with IPv6 support”？

itpro_zhang

大家好，

近期有几台部署了相同应用的服务器陆续发生自动重启，OS kernel: 2.6.32.12-07 , suse 11 sp1 enterprise x86_64。
应用的研发那边怀疑与IPV6相关，但需要确认 “You have to ensure your kernel is compiled with IPv6 support.”
请问：
1、这句话应该如何理解？
2、如何（用什么命令）确认内核是否“compiled with IPv6 support”？

多谢各位

附重启时段的system log

grep -i ipv6 /boot/config-xxxx

检查下内核里面是否有v6支持

谢过两位，我不是做Linux的，不大熟，所以特来求教

这是什么情况 ?
