02/02/2023, 3:57 PMHi all! I have got a kind of a FAQ problem all over again, but no known solutions are helping... So I have a Pants project that I had on hold, and now got back to it. It had been working before, but now it doesn't anymore. I have a Python script that executes a couple of pants commands, to check some dependencies. Running it manually works ok, but running it via "PANTS_CONCURRENT=True ./pants run " doesn't, I get "Failed to begin watching the filesystem: Too many open files (os error 24)". This is with pants 2.14.0. Has anyone any suggestions about why it doesn't work anymore? Should I just find another way to run the script?

02/02/2023, 4:24 PMThis is a bit FAQy indeed. What steps did you take to solve too many open files in the past or in the current. Did you search on pantsbuild.org?

02/02/2023, 4:26 PMI'm holding back a link in case you can't find it, but you definitely get a search hit on that; so I'm wondering if you did that in the past, followed the instructions and are now hitting the issue again?

02/02/2023, 5:21 PMIn the interest of async communications, that googleable link leads here: https://www.pantsbuild.org/docs/troubleshooting#too-many-open-files-error
Please let us know if you had already found this and tried bumping your ulimits.

02/02/2023, 6:04 PMYes, I have done all the suggestions in the FAQ, I have ulimit set to 100000 in the pants script, have checked /etc/security/limits.conf (or whatever it is called), etc. That information disappeared from my initial message when I edited it a bit. It gives the error only when I call the script "pants run", but it has been working before. I don't know what could have had changed since then...

02/02/2023, 6:15 PMThe characters are very important here. You mean exactly
pants runpants./pantsenough-analyst-54434
02/02/2023, 6:16 PMIf so, that explains it.

02/02/2023, 6:17 PMYou'll need to set ulimit elsewise.

02/02/2023, 6:17 PMI used "PANTS_CONCURRENT=True ./pants run myscript.py", like I mentioned in the initial post. And myscript.py uses subprocess.run() to call "./pants --filter-target-type=pex_binary list ::"

02/02/2023, 6:19 PMOk, gotcha. So the later "pants run" was a typo / abbreviation. Well, since you still use
./pantsenough-analyst-54434
02/02/2023, 6:20 PMSomeone else will have to help you from here. I need to be AFK for a while.
