为什么libcore.io.ErrnoException：kill失败：在android中ESRCH(没有这样的过程)？

try {
Runtime rnTm=Runtime.getRuntime();
Process execLang = rnTm.exec(new String[]{"getprop","persist.sys.language"});
mCurrLocale = new BufferedReader(new InputStreamReader (execLang.geTinputStream())).readLine();
execLang.destroy();
Process execCountry = rnTm.exec(new String[]{"getprop","persist.sys.country"});
mCurrCountry = new BufferedReader(new InputStreamReader    (execCountry.geTinputStream())).readLine();
execLang.destroy();
Log.e("","Device locale: "+mCurrLocale+" Co:"+mCurrCountry);
} catch (IOException E) {
 e.printStackTrace();
 return;
 }
catch (S@L_607_1@Exception sE) {
    se.printStackTrace();
return;

}

It's working fine some phones and tablet.

但有一段时间它导致我的应用程序冻结并在logcat中给出以下结果.

I/System  ( 1511): Failed to destroy process 1547
I/System  ( 1511): libcore.io.ErrnoException: kill Failed: ESRCH (No such process)
I/System  ( 1511):      at libcore.io.Posix.kill(Native Method)
I/System  ( 1511):      at libcore.io.ForWARDingOs.kill(ForWARDingOs.java:77)
I/System  ( 1511):      at      java.lang.Processmanager$ProcessImpl.destroy(Processmanager.java:257)

有什么解决方案吗？
