EX_OSFILE

EX_OSFILE

---

A critical system file failure

sendmail exit value

The EX_OSFILE exit code (value 72) results when certain system files could not be opened and when certain system programs could not be executed.

When sendmail gets a SIGHUP signal, it attempts to re-execute itself (SIGHUP). If it fails, the following error is logged and sendmail exits:

 could not exec  /path/sendmail  :  reason  

The sendmail program can run a program to look up a key in a database. If sendmail fails to run the program, it prints the following error:

 prog_map_lookup(  program  ) failed (  reason  ) -- closing 

We probably don't have to mention this, but the sendmail program has to read its configuration file. If it fails to open , stat, or read that file, or if that file is not a plain file, it prints one of the following errors (depending on your version of sendmail ) and exits with an EX_OSFILE value:

 cannot open cannot fstat not a plain file I/O read error  filename  : cannot open  reason   filename  : cannot fstat  reason   filename  : not a plain file  reason   filename  : I/O read error  reason
