Ok. I got a new one today and I'm leaving it around so we can figure this thing out. Here's the cron tree: 3480 ? Ss 0:01 crond 16571 ? S 0:00 \_ crond 16572 ? Ss 0:00 \_ /usr/bin/perl -w /usr/bin/flexbackup -set backup -incremental 16846 ? Z 0:00 | \_ [sh] <defunct> 16573 ? S 0:00 \_ /usr/sbin/sendmail -FCronDaemon -i -odi -oem -oi -t And here's the gzip: 16860 ? S 0:01 gzip -9 and ps -ef shows root 16860 1 0 03:31 ? 00:00:01 gzip -9 root 16571 3480 0 03:31 ? 00:00:00 crond root 16572 16571 0 03:31 ? 00:00:00 /usr/bin/perl -w /usr/bin/flexbackup -set backup -incremental smmsp 16573 16571 0 03:31 ? 00:00:00 /usr/sbin/sendmail -FCronDaemon -i -odi -oem -oi -t root 16846 16572 0 03:31 ? 00:00:00 [sh] <defunct> which shows that gzip is now the child of init which means that his parent exited and orphaned him. And 16846 seems to not be getting cleanup up by flexbackup. Anyone have an idea of what this all means? -- Time flies like the wind. Fruit flies like a banana.
