不懂就问 · 2021 年3 月 24 日 09:06

是什么版本的 tiflash？可以看下是否是 OOM 引起的重启，如果可以排除 OOM 问题导致的，可以看下 TiFlash log 下面日志信息或者传一份到帖子里。

Hacker_2SoDekMm · 2021 年3 月 24 日 09:19

不是OOM引起的，tiflash.log 日志如下。我下掉了昨天添加的一个表，tiflash暂时不再重启了，但不知道什么原因

Hacker_2SoDekMm · 2021 年3 月 24 日 09:20

日常tiflash会有以下警告，但也不是影响重启的原因

yilong · 2021 年3 月 26 日 03:05

message 日志里有什么信息吗？

Hacker_2SoDekMm · 2021 年3 月 26 日 06:10

只有这点信息，没有有价值的

yilong · 2021 年3 月 29 日 02:25

好的，多谢，如果下次可以复现问题，麻烦继续反馈。

windtaker · 2021 年5 月 13 日 04:37

请问这个问题现在还存在吗，看这个log是substring函数有bug导致tiflash segment fault了

@Hacker_2SoDekMm 希望有进展反馈一下，感谢啦～
