This message probably comes from the following fragment within
$PTOLEMY/src/kernel/Display.cc:
for (int i = 0; i < ng; i++) {
tmpFileNames[i] = tempFileName();
count[i] = 0;
// open and make sure the file is writable
if ((strm[i] = fopen(tmpFileNames[i], PT_FOPEN_WRITE_BINARY))
== NULL) {
StringList msg = "Can't open temporary file for writing: ";
msg << tmpFileNames[i];
Error::abortRun(*blockIamIn, msg);
}
}
The error is occurring because fopen() is failing to open the file.
You might want to have a look at the fopen() man page for possible
reasons. Perhaps your /tmp is full.
Perhaps you need to increase the number of open files you can have
See the limit command man page for more info

I modified the Display.cc sources so that it will print the reason why
fopen() failed

I have a large simulation with a lot of xmgraph stars.
When I try to run my simulation, I have an error message :
Error: XMgraph.input=12 : Can't open temporary file for writing :
/tmp/pt01d9.1234
What does it mean please ?
Does It mean that I have too many xmgraphs in my simulation ?
Thank's for your help.
