asp.net - Error : Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool -


we having error in our developed asp.net application. error below. deployed application many customers. 1 of them getting error every day. set max pool size tp 6000 in connection string error keeps occuring. i've analyzed data access layer closing connection strategy. there's no mistake in dal. when error thrown, executed sp_who or sp_who2 stored proceducer. there no open connection , connection list has average of 50-60 quantities. tried every method can't resolve problem.

i'm having error since server changed sql 2008 r2 sql 2012.

i suspect server has been changed or .net framework version.

there error either caused running out of connections in pool if have set pool size 6000 (eeeek) won't that.

the second cause connection timeout sql box, default 15 seconds should plenty can try increasing , see if less errors - if there wrong sql or connection between server , database.

please please please make sure have our sqlconnections inside using blocks , being put in pool.
