sql server - SqlClient.SqlException .Number = 3617 .State = 68 -


we receiving exception 1 of our sql select statements. cannot find error 3617 in sysmessages table. .class 25. there no message.

we know getting on sql server 2005 servers.

i know large select joins several tables , uses clr combine , order data.

what causing error or find out error code means?

take @ this: discussion on microsoft forums, see answer moderator last in post.

updated: (added text forum post):

error code 3617 system attention. system attention occurs when client cancels running request. can happen if command times out example. error not sent client however.

there special case can occur may hitting. when re-use pooled connection, first outbound request sends special bit flag on request tell server reset connection state prior executing request. bit causes server first clear connection state, execute command. if sql server under heavy load, , bit set, , takes long time reset connection state, client may timeout , send system attention. causes reset of connection cancelled , in case can see 3617 sent client.

we've hardened code in current release avoid sending specific error code error spurious in nature (based on timing may or may not error). in case, can consider error equivalent to: "a severe error occurred on current command. results, if any, should discarded. operation cancelled user."

to verify if issue, examine sql errorlog error below:

spid51 task abort requested while attempting reuse session spid 51, has been reset connection pooling. session terminated.
