【问题描述】：
我的网络应用程序有时会开始抛出以下错误。
使用 NHibernate 4.0.0.4000 和 MySql.Data 6.8.3
堆栈跟踪
ERROR [(null)] - Message:could not execute query
一旦出现这些错误，它就会开始频繁发生，直到重新启动 Web 应用程序。
奇怪的是，它只发生在部分用户身上，而不是所有用户身上。我还注意到在这个特定的日志消息中 p4 和 p5 的值应该交换。
这是查询缓存的问题吗？
有人知道为什么会这样吗？
如果它有帮助，那就是粗糙的查询（但我在更简单的查询中也看到了这个错误）
FunderInfoViewModel funderDto = null;
Funder funderAlias = null;
Contact contactAlias = null;
var totalOpportunitiesAwardedCount = QueryOver.Of<Opportunity>()
.Where(o => o.Funder.Id == funderAlias.Id)
.And(o => o.Status == OpportunityStatus.Awarded || o.Status == OpportunityStatus.AwardedClosed)
.SelectList(list => list
.SelectCount(o => o.Id));
var totalOpportunitiesAwardedSum = QueryOver.Of<Opportunity>()
.Where(o => o.Funder.Id == funderAlias.Id)
.And(o => o.Status == OpportunityStatus.Awarded || o.Status == OpportunityStatus.AwardedClosed)
.SelectList(list => list
.SelectSum(o => o.AmountAwarded));
var totalOpportunitiesCount = QueryOver.Of<Opportunity>()
.Where(o => o.Funder.Id == funderAlias.Id)
.SelectList(list => list
.SelectCount(o => o.Id));
IEnumerable<FunderInfoViewModel> funders = _session.QueryOver(() => funderAlias)
