Describe the bug
for example , if a log file is "abcd"
sometimes it can only collect "abc"
this is my code

tails, err := tail.TailFile(fileName, tail.Config{ ReOpen: true, Follow: true, Location: &tail.SeekInfo{Offset: 0, Whence: flag.Whence}, MustExist: false, Poll: false, })

Expected behaviour

To Reproduce
sry ,I have used this to collect over a million log entries, and only a few hundred of them are difficult to reproduce.

System information

• tail version [v1.4.8]
• OS: centos
• Arch: [e.g. arm64]

I'm experiencing a similar issue.
In my case I'm tailing a fast-changing file with up to 4 milions of entries.
However it seems to me that this is more related to the speed at which the file is appended to, rather than the volume of the file itself.

• Tail version: v1.4.8 and v1.4.11
• OS: Ubuntu 20
• Arch: x86_64

Edit:
Upon inspection, it seems that setting this might work: Tail.Config.CompleteLines = true

[szuro]

After running with CompleteLines=true for >24h, I see no issues with incomplete lines.

It' s weird when follow=true I would need also CompleteLines=true to make it work.
