bus error

[beibeiabeibei]

my program is running in K8S,and it core dump once a week to three weeks.

//main.go
func main() {
        initLog()
       ....
       ....
} 

func initLog() {
        logger, err := seelog.LoggerFromConfigAsFile(startcfg.GetWSerLogPath())
        if err != nil {
                panic(err)
        }
        if err = seelog.ReplaceLogger(logger); err != nil {
                panic(err)
        }
}
