Hello
Like I said before you need to use the latest version of the IGS files.
This is what I see:
trc file: "/usr/sap/R3U/DVEBMGS06/igs/log/mux_sapux1.trc", trc level: 1, release: "700"
I suggest you to stop the SAP system an clean up all the processes and then start the SAP system.
1799603 - Error When Calling IGS "IGS error:ProcessChartRequest (RFC_EXTERNAL_FAILURE)"
1491848 - What IGS should I be using with my Web AS?
If the IGS fails after putting the new version of the OGS files upload the latest trace files from the /usr/sap/SID/DVEBMGS00/igs/log location.
Regards
RB
