I am using a simple UCI program (tt1.c) with Xmath version 7.0.1 on Sloaris 2.8 that performs the followings:
- Start Xmath701
- Sleep 10 Seconds
- Load a sysbuild model
- Stop Xmath
I am calling the uci executable using the following command:
> /usr/local/apps/matrixx-7.0.1/bin/xmath -call tt1 &
In this way everything works fine and the following printouts from the program are produced.
--------- uci printout ----------
## Starting Xmath 701
## sleep 10 seconds
## load "case_h_cs_ds.xmd";
## Stopping Xmath 701
-----------------------------
All the processes (tt1, XMATH, xmath_mon, and sysbld) terminate correctly.
The problem occurs if the 10 second wait after starting xmath is omitted:
- Start Xmath701
- Load a sysbuild model
- Stop Xmath
This results to the following printouts:
--------- uci printout ----------
## Starting Xmath 701
## load "case_h_cs_ds.xmd";
Assertion failed: file "/vob1/xm/ipc/ipc.cxx", line 420 errno 0.
-----------------------------
Note that the last line is not produced by the uci program and the tt1 did not
finish (the printout before stopping xmath "## Stopping Xmath 701" was
not produced).
A call to the unix "ps -ef" utility shows that none of the related process has been terminated:

The questions are as follows:
1- What is "Assertion failed: file "/vob1/xm/ipc/ipc.cxx", line 420 errno 0" and why is that produced?
2- Should the UCI program waits for end of sysbld initialization before issuing commands?
3- If the answer to the above question is yes, is there a way to check the termination of sysbld initialization?
Thanks in advance for you help.
