[dtrace-discuss] DTrace instrumental in exposing Sendmail bug

[Nik Clayton]

I thought you might like to know that DTrace has been instrumental in 
exposing a bug in Sendmail.

The bug is to do with how Sendmail processes multiple queue directories. 
  As documented, Sendmail is supposed to start one queue runner per 
configured directory.  But a regression introduced some time ago means 
that only one queue runner is ever created.

Thanks, DTrace.
