For the last few days, sendmail has been generating an enormous temp file, which is deleted, but still linked by the application.

Here is the output of lsof -a +l1 /

COMMAND    PID USER   FD   TYPE DEVICE      SIZE/OFF NLINK     NODE NAME
sendmail 10547 root    0r   REG  253,0 2058224971776     0 30670859 /tmp/fileeteaAd (deleted)

You can see the file is 2.05 TB (which is the size of the disk). How do I go about debugging this to see how this is happening, and is there a way to configure sendmail so that it can't do this? This server has been running for years without issue until recently.

Centos 6.2, I can't seem to figure out how to get the sendmail version.

  • rpm -qf $(which sendmail) should tell you the package. – thrig Oct 25 '16 at 13:50
