Question is: the first stack trace is irrelevant to others, what happened? Any ideas?
Let me make this more clear:
a MVC page uses the spring part trying to load a lazy-init service which constructor wants a connection string through a static property like this:
<object id="promotionRepos" type="ECommerce.Data.AdoNet.Promotions.PromotionRepos, ECommerce.Data.AdoNet" lazy-init="true">
<constructor-arg name="provider">
<null />
</constructor-arg>
<constructor-arg name="connStr">
<object type="ECommerce.ERP.DAL.DBConn, ECommerce.ERP.DAL" factory-method="get_ConnString" />
</constructor-arg>
<property name="RefreshInterval" value="00:00:10" />
</object>
the timeout part is some what irrelevent to all others. see this in the first exception: Shopping_Shopping.Page_Load(Object sender, EventArgs e) +10
it's another page at all. And also, ECommerce.PMethod.Sql.SqlConns.Open() uses its own connection string, not the one loaded by spring, it's different module from diffrent team. And I am sure the connection string is correct.
And, this ysod cames up randomly. Sometimes nothing is wrong, and sometimes, it appears.
I thought there could be something wrong with my database or the network/firewall, I will check it later, but now I want understand this tricky stack trace.
