Max open outbound sockets per request error during product transport

Hello,

I am attempting to transport a product with multiple delivery units in the transport manager from a remote system via HTTPS.  Each time I try to do this transport it fails at the same place. The error in the transport web interface is that the source system is unavailable.

In looking at the XSJS logs I see the following:

12: 0x00007fb2c9f3269d in Execution::Thread::staticMain(void*)+0x39 at ThreadMain.cpp:26 (libhdbbasis.so)

[14008]{-1}[-1/-1] 2015-10-24 06:08:32.152502 e xsa:sap.hana.xs. sap.hana.xs.lm.xsts:utils.xsjslib(00694) : HTTP Request failed. ERROR: (new Error("HttpClient.request: Max open outbound sockets per request reached.", "/sap/hana/xs/lm/xsts/utils.xsjslib", 642))

[14008]{-1}[-1/-1] 2015-10-24 06:08:32.160295 e xsa:sap.hana.xs. sap.hana.xs.lm.core:TransportServiceBaseLib.xsjslib(00390) :

Stack Trace:

UserReportableException@/sap/hana/xs/lm/xsts/utils.xsjslib:42

@/sap/hana/xs/lm/core/TransportServiceBaseLib.xsjslib:67

@/sap/hana/xs/lm/core/TransportService.xsjs:14

The source system is running HANA SPS 09 Rev 96 and the target system is running SPS 10 Rev 101.

Does any one have suggestions on what could be happening here? Is this an issue with the system configuration of the target system? It seems like the transport process is making too many requests at once when fetching the DUs.

Thanks

    Hi Eric,

    We're facing the same error.

    We're running with both source and target as SPS10 rev 102.

    If we figure it out I'll let you know.

    Hi Eric,

    Have you managed to fix this issue? We experience the same problem while making https requests to third party service.

    Hi All,


    We also found out that:


    It probably has something to do with the .close() method of HttpClient:

    http://help.sap.com/hana/SAP_HANA_XS_JavaScript_API_Reference_en/$.net.http.Client.html

    which however does not seem to be available in SP10.


    But increasing max_open_sockets_per_request undocumented setting xsengine.ini: [communication] - max_open_sockets_per_request may also help.




    Best,

    Anton
