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.cpp2897]
*** 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.cpp2897]
*** 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
