After checking with jhb@ re appropriate value of __FreeBSD_version for the test, I have submitted a build configuration patch to the sendmail folks so that a sendmail build on FreeBSD >= 300000 will use nanosleep(). The patch has been accepted by sendmail and is attached for reference. > SERVER 1 > - FreeBSD 8.0-RELEASE-p2 > - Sendmail 8.14.4 (modified so that sleep() uses nanosleep(2)) > > SERVER 2 > - FreeBSD 8.0-RELEASE-p2 > - Sendmail 8.14.4 > > SERVER 3 > - FreeBSD 8-STABLE > - Sendmail 8.14.4 > > ...and then watch sendmail on all three. One week has elapsed and no queue runners have succumbed to excessive drowsiness. -- John Marshall
