Description

间歇性出现内核崩溃,提示"panic: connection already exists" clash检测到内核崩溃自动重启后,可正常运行,到17:00未再次出现,目前可正常使用

dycwuxing commented 1 year ago

更新内核到"alpha-d6b80ac" 问题依旧,这次观察了下:早上重启后内存150MB左右,到中午看的时候内存到500MB左右,后来再看就崩了,应该是内存泄露了?

dycwuxing commented 1 year ago

更新alpha-7286391和上一个版本后内存还是会不停的涨,但是提示有变化提示"protocol error: received DATA before a HEADERS frame"

dycwuxing commented 1 year ago

heap.zip传过了,大佬们啥时候能给看看啊?现在最新内核"21fb5f7.gz",不到4个小时,就会爆内存崩一次

Skyxim commented 1 year ago

@dycwuxing alpha 已经更新过多次 quic-go 可以尝试最新版本是否存在崩溃

snakem982 commented 10 months ago

这个是因为quic基础包中的一个文件会panic https://github.com/quic-go/quic-go/blob/master/multiplexer.go 具体代码如下

func (m *connMultiplexer) AddConn(c indexableConn) {
    m.mutex.Lock()
    defer m.mutex.Unlock()

    connIndex := m.index(c.LocalAddr())
    p, ok := m.conns[connIndex]
    if ok {
        // Panics if we're already listening on this connection.

        // We'll remove this at a later time, when most users of the library have made the switch.

    m.conns[connIndex] = p
}
