跟踪源码发现异常来源于此方法
```
private void guardedWait(Invocation invocation) throws InvocationException {
long wait = getWaitTime(invocation);
try {
if (wait <= 0) {
latch.await();
return;
}
if (latch.await(wait, TimeUnit.MILLISECONDS)) {
return;
}
} catch (InterruptedException e) {
//ignore
}
throw new InvocationException(REQUEST_TIMEOUT,
ExceptionCodes.INVOCATION_TIMEOUT, "Invocation Timeout.");
}
```
latch.wait时，线程处于中断状态，导致抛出异常，请问这种问题该如何排查
