Check what's being ran inside those 100 concurrent jobs.
Are you really running 100 jobs concurrent jobs ?
Are they finishing properly ?
If all above is correct then increase concurrent jobs limit, unless you want the same to happen with 200 (or any) limit in future time
It's likely that some of that jobs are not exiting or hanging, occupying the one of the cron job
slots forever ( until cron or machine is restarted/rebooted )

set::crontab
Crontab(3pm) User Contributed Perl Documentation Crontab(3pm)
NAME
Set::Crontab - Expand crontab(5)-style integer lists
SYNOPSIS
$s = Set::Crontab->new("1-9/3,>15,>30,!23", [0..30]);
if ($s->contains(3)) { ... }
DESCRIPTION
Set::Crontab parses crontab-style lists of integers and defines some utility functions to make it easier to deal with them.
Syntax
Numbers, ranges, *, and step values all work exactly as described in crontab(5). A few extensions to the standard syntax are described
below.
< and >
<N selects the elements smaller than N from the entire range, and adds them to the set. >N does likewise for elements larger than N.
! !N excludes N from the set. It applies to the other specified range; otherwise it applies to the specified ranges (i.e. "!3" with a
range of "1-10" corresponds to "1-2,4-10", but ">3,!7" in the same range means "4-6,8-10").
Functions
new($spec, [@range])
Creates a new Set::Crontab object and returns a reference to it.
contains($num)
Returns true if $num exists in the set.
list()
Returns the expanded list corresponding to the set.
The functions described above croak if they are called with incorrect arguments.
