java计划任务导致OutOfMemoryError（Spring引导）

Question

应用程序工作正常，直到计划的任务在后端启动。此任务更新云数据库中的帖子，如果有更改，则重写现有帖子。在更新了大约400-500篇帖子后，应用程序崩溃了H2数据库，并给出了一个错误：线程“File Watcher”java中出现异常。lang.OutOfMemoryError:Java堆空间

我预定的任务

 @Scheduled(cron = "0 0 15 ? * SUN")
  public void updateAllWeekly() {
    log.debug(
        "<< UPDATE ALL >> CRON IS STARTED. The time is now {}", dateFormat.format(new Date()));
    postService.updateAll();
  }

updateAll方法

  public void updateAll() {

    try {

      Long startId = 0L;

      do {
        startId = updateFrom(startId);
      } while (startId > 0);

    } catch (FeignException ex) {
      log.debug("CALL ERROR", ex.contentUTF8());
      return;
    }
  }

updateFrom方法

public Long updateFrom(Long startId) {

    Long lastd = startId;

    try {
      List<Post> posts = cloud.pullPostsFromId(startId)
      int postSize = posts.size();

      if (postSize > 0) {
        lastd = posts.get(postSize - 1).getId();
      } else {
        startId = -1L;
        return startId;
      }

      for (Post post : posts) {

        updatePost(post);
      }

    } catch (FeignException ex) {
      log.debug("CALL ERROR");
    }

    return lastd + 1;
  }

updatePost方法按id（Post.getId）查找Post，设置更改的参数（如果有），并将其保存回数据库

完全错误：
