jpa应用程序在运行数小时后不会从对jpa存储库的调用返回

我有一个应用程序在开发中使用springbootjpa和mysql数据库都在windows10上。
应用程序通常运行良好，但有时在中运行数小时后，无法从对jpa存储库的调用返回。
process explorer显示最小的cpu/io活动。应用程序中的其他线程继续访问数据库而没有问题。
我几乎不知道从哪里开始寻找问题，欢迎任何建议。
我的存储库定义是：

@Repository
public interface TradeRepository extends JpaRepository<TradeDbo, Long>{ 
  ... 
  @Query("select t.tradeId from TradeDbo t where t.currencyPair.id = :currencyPairId") 
  HashBag<String> getTradeIdListByCurrencyPairId(@Param("currencyPairId") Long currencyPairId);
}

调用代码是：

log.trace("Entering tradeRepository.getTradeIdListByCurrencyPairId");
Bag<String> tradeIdsInDb = tradeRepository.getTradeIdListByCurrencyPairId(currencyPairId);
log.trace("Back from tradeRepository.getTradeIdListByCurrencyPairId");

正常的日志条目是：

2018-09-30 00:34:12,458 TRACE [TradesFetcher-Gdax] [CoinDbService.java:484] biz.ianw.coindatabase.services.data.CoinDbService - Entering tradeRepository.getTradeIdListByCurrencyPairId
2018-09-30 00:34:20,509 TRACE [TradesFetcher-Gdax] [CoinDbService.java:486] biz.ianw.coindatabase.services.data.CoinDbService - Back from tradeRepository.getTradeIdListByCurrencyPairId

但是当它挂起来的时候我会得到这样的东西：

2018-09-30 00:34:22,732 TRACE [TradesFetcher-Gdax] [CoinDbService.java:484] biz.ianw.coindatabase.services.data.CoinDbService - Entering tradeRepository.getTradeIdListByCurrencyPairId

...

直到我打破它（^c），然后我得到：

2018-09-30 05:11:13,441 WARN  [TradesFetcher-Gdax] [ProxyConnection.java:161] com.zaxxer.hikari.pool.ProxyConnection - HikariPool-1 - Connection com.mysql.jdbc.JDBC4Connection@57ee5254 marked as broken because of SQLSTATE(08S01), ErrorCode(0)

最后几行显示了prepared语句的执行，以及kill时的堆栈跟踪，暗示了语句执行中的一些问题，但我不清楚这是bug还是资源耗尽。
更新
今天的测试在运行不到2小时后，在另一个地方出现了一个错误，即保存：

2018-10-01 11:40:33,458 INFO  [TradesFetcher-Gdax] [CoinDbService.java:504] biz.ianw.coindatabase.services.data.CoinDbService - Saving...
2018-10-01 17:28:11,066 INFO  [Thread-6] [Shutdown.java:12] biz.ianw.coindatabase.Shutdown - TradesFetcher-Gdax: shutdown hook started

log.info("Saving...");  
currencyPairRepository.save(currencyPairDboToProcess);
log.info("Save complete");

此测试还包括添加60秒超时，但没有效果：

@Transactional(readOnly=false, rollbackFor=Exception.class, timeout=60)

我打开了log4jdbc选项：

logging.level.jdbc.sqlonly=info
logging.level.jdbc.connection=info

我再次跑去看看，如果我能从中学到什么的话。。。
更新
显然很少。跑了3个半小时，挂在不同的地方：

03:35:44.208 INFO  [TradesFetcher-Gdax] [Slf4jSpyLogDelegator.java:228] jdbc.sqlonly - insert into trade (creation_date, last_modified_date, currency_pair_id, original_amount, price,

按热度按时间
n8ghc7c1

n8ghc7c11#

这似乎是由我使用的spring引导包中的底层hikari和/或jdbc驱动程序引起的。更新hikari给了我一个关于jdbc无法检查连接是否仍然有效的警告，并且更新驱动程序使这个警告消失了。从那以后，我就再也没有在测试中遇到什么问题了。
