The error was: \[code\]Cannot run program "chmod": java.io.IOException: error=24, Too many open files\[/code\] While, “too many open files” usually means one can raise the limit of open files under Linux (check out ulimit -a) it unfortunately did not help in this situation. I even rebooted the whole server and made sure that no other service was running, except Java that is. Still no success. I then looked at my code in the CFML (Coldfusion) template. In order to create the directories I used a simply: \[coldfusion\]\[/coldfusion\] Normal code, right? Well, as it turns out, I simply had to remove the “mode” part in order to overcome this error. Not sure, why this caused a “too many open files” error, but it worked in my situation. I can only imagine that the server tried to put all 2000 directories into memory and then write them in one go (I have a high value for the open files limit set and 12GB RAM). In any case, hope this helps someone out here.
