I've seen that happen before. Looks like a race condition of some sort since there is a test just before that checking for the file, and touch should create a file if it doesn't already exist. I've never seen a problem come from it, just the error, so it's just something we can suppress.

It might be a permission issue, php docs about file_exists() states:
"The check is done using the real UID/GID instead of the effective one."but the file is probably created using the "effective one". Would the more appropriate is_file() be a workaround to skip the permission issue?

If that were the case it would happen to everyone all the time, which isn't true. Also the order of operations is backwards compared to your theory. In the code, the file tested to see if it does not exist before it is touched -- touching a file that doesn't exist will create a new/empty file, and if the file exists it updates the time. Which is why it sounds more like a race condition where several processes have been triggered at once, and the file is somehow removed while touch() is in the middle of working on it.

I gave a look at PHP source code and I have a doubt, what is the gateway name?
