Symfony\Component\Process
I'm getting this error after running a process for a long time
A temporary file could not be opened to write the process output to, verify that your TEMP environment variable is writable
Seems to be the windows workaround in getDescriptors()
I found the problem to be 65,000 temp files created by this file in my windows temp but not removed. I have to clear these out daily.
PHP should remove the files but they slowly build up.
