Operating system call connect failed (error no. 79 )

I had 2 instances, instance number 41 and 42. I just remove instance 42 (dialog instance).

After that, every 5 minutes I receive error in SM21. The error :

Operating system call connect failed (error no. 79 )

NiConnect Unsuccessful, Return Code: -0010

> Host: SAPEPRD10

> Service: sapgw42

I check trace in SMGW :

(SI_ECONN_REFUSE/79; I4; ST; 10.91.10.59:3342) [nixxi.cpp 2897] *** ERROR => GwIAsyncConn: GwBufConnect to SAPEPRD10 / sapgw42 failed (rc=NIECONN_REFUSED) [gwxx.c 1281] ***LOG S0T=> GwIAsyncConn, GwBufConnect (-0010) [gwxx.c 1283] ***LOG S0R=> GwIAsyncConn, GwBufConnect () [gwxx.c 1285] ***LOG S0S=> GwIAsyncConn, GwBufConnect (sapgw42) [gwxx.c 1287]

It's the same content in dev_rd :

(SI_ECONN_REFUSE/79; I4; ST; 10.91.10.59:3342) [nixxi.cpp 2897] *** ERROR => GwIAsyncConn: GwBufConnect to SAPEPRD10 / sapgw42 failed (rc=NIECONN_REFUSED) [gwxx.c 1281] ***LOG S0T=> GwIAsyncConn, GwBufConnect (-0010) [gwxx.c 1283] ***LOG S0R=> GwIAsyncConn, GwBufConnect () [gwxx.c 1285] ***LOG S0S=> GwIAsyncConn, GwBufConnect (sapgw42) [gwxx.c 1287]

How can I fix this problem?

Thank you

    Hello,

    Error 79 means Connection Refused.

    The "Connection Refused" error means that the host can be reached but the port is not bound on this host. If you check the gateway trace file dev_rd you should find more details on the error, for example
    you should be able to see the host and port number involved.

    When the problem happens try and connect to the server and port from where the error occurs:

    niping -c -H hostname -S portnumber

    Also check if the host and port are resolved to the correct value (also on the host where the error occurs)

    > niping -v -H hostname
    > niping -v -S sapgwXX

    If the niping fails, please check the Network for errors and also
    ensure that the correct port is used.

    Also ensure there is an entry for sapgwXX in the services file.

    Regards,

    Fionnuala
