Informix Error -33083: Cannot open file file_name because of too many open files.

Cause and resolution

Cannot open file file_name because of too many open files.

The preprocessor cannot open the file because too many files are open. Check your system resources to see if you can increase the number of file handles (descriptors). Close unnecessary open files. Also check for mistakes that might cause recursive file inclusion.

Reasons / Common Causes

-33083 fires when the preprocessor can't open a file because the process has too many files already open — per the official guidance.

  1. The process's open-file limit reached, per the official guidance — the first named cause.
  2. Recursive file inclusion, per the official guidance — a possible underlying mistake causing excessive open files.
Solutions / Resolution
  1. Check system resources and increase the number of file handles/descriptors if possible, per the official guidance.
  2. Close unnecessary open files, per the official guidance.
  3. Check for a mistake causing recursive file inclusion, per the official guidance.
