I know it is unlikely, but has anyone checked whether or not the server is running at 6am on the day(s) when the cron job doesn't run? If there is some kind of daily maintenance operation that takes the server out of normal multi-user mode during that timeframe, cron jobs that were missed while not in multi-user mode will not be started if the system comes back up to normal multi-user mode after the job's scheduled start time.

The .profile file should be read when the user logs in. So, there should be no need to execute .profile file again in a cron job (since the cron job is run after the user logs in). Doesn't the cron require login from the user. Then, from where does the cron execute? Please help!! (1 Reply)

queuedefs
queuedefs(4) Kernel Interfaces Manual queuedefs(4)NAME
queuedefs - queue description file for at, batch, and crontab
SYNOPSIS DESCRIPTION
The file describes the characteristics of the queues managed by (see cron(1M)). Each non-comment line in this file describes one queue.
The format of the lines are as follows:
[njob[nice[nwait
The fields in this line are:
q The name of the queue, such that is the default queue for jobs started by (see at(1)), is the queue for jobs started by
(see at(1)), and is the queue for jobs run from a file (see crontab(1)). Queue names through designate user-defined
queues.
njob The maximum number of jobs that can be run simultaneously in that queue. Although any number can be specified here, (see
cron(1M)) by default limits the number of jobs that can be run on all the queues to 100. This limitation can be removed
by setting the variable to 1 in the file.
nice The value to give to all jobs in that queue that are not run with a user ID of super-user (see nice(1)). The default
value is 2.
nwait The number of seconds to wait before rescheduling a job that was deferred because more than njob jobs were running in that
job's queue, or because more than 100 jobs were running in all the queues (see njob above).
EXAMPLES
Consider the following file:
The file is interpreted as follows:
The queue, for jobs (see at(1)), can have up to 4 jobs running simultaneously, and those jobs will be run with a value of
1.
Since no nwait value is given, if a job cannot be run because too many other jobs are running, will wait 60 seconds
before trying again to run it (see cron(1M)).
The queue, for jobs (see at(1)), can have up to 2 jobs running simultaneously. Those jobs will be run with a value of 2.
If a job cannot be run because too many other jobs are running, will wait 90 seconds before trying again to run it.
All other queues can have up to 100 jobs running simultaneously. They will be run with a value of 2, and if a job cannot be run because
too many other jobs are running, will wait 60 seconds before trying again to run it.
