Error in SM21 and in dev_ms trace file.

Hi All,

I am facing a issue in our BI 7.0 system.

The error is shown in SM21 transaction as : operating system call connect failed (error no. 239 ).

And if i check the file in dev_ms trace file i found this error message

[Thr 01] *** ERROR => NiBufIIn: message length 1933714725 exceeds max (8388608;hdl 4;peer=156.70.6.219:57448) [nibuf.cpp 3074]

May i know how do i get rid of the error.

Thanks,

NT
