High number of "Network error code 0x2746" in extended events log RRS feed

  • Question

  • In the extended event log of our database server I see 880 consecutive identical errors, all occurring between

    17:00:49 and 17:15:25. The message is:

    Network error code 0x2746 occurred while establishing a connection; the connection has been closed. This may have been caused by client or server login timeout expiration. Time spent during login: total 27 ms, enqueued 0 ms, network writes 0 ms, network reads 25 ms, establishing SSL 8 ms, negotiating SSPI 0 ms, validating login 0 ms, including user-defined login processing 0 ms. [CLIENT: 10.127.214.32]

    The timings in each message are a little bit different. It might be interesting to know the averages for these timings, so here is the message again, now with the timings replaced by averages (rounded to 1 digit):

    Network error code 0x2746 occurred while establishing a connection; the connection has been closed. This may have been caused by client or server login timeout expiration. Time spent during login: total 32.5 ms, enqueued 0.5 ms, network writes 0.9 ms, network reads 29.4 ms, establishing SSL 8.3 ms, negotiating SSPI 0.0 ms, validating login 0.0 ms, including user-defined login processing 0.0 ms. [CLIENT: 10.127.214.32]

    The client is a Citrix server that runs a COTS program. It serves approx. 20 users.

    What can be the cause of this? Can it only be the program that automatically tries to reconnect?
