​Probably a silly idea, but is it possible that your system's /var/cron is a 
mount point and a different zFS data sets is mounted upon it? Easiest way that 
I know of to check this is from a UNIX shell and issue the command:

df -v /var
df -v /var/cron

As an example (my /var/log is on a different zFS than /var)

​$ ​
df -v /var
Mounted on     Filesystem                Avail/Total    Files      Status

/LIH1/var      (OMVS.I17RS1.LIH1.VAR)    28576/40320    4294967137 Available
ZFS, Read/Write, Device:7, ACLS=Y
File System Owner : LIH1        Automove=U      Client=N
Filetag : T=off   codeset=0
Aggregate Name : OMVS.I17RS1.LIH1.VAR
$
​ ​
df -v /var/log
Mounted on     Filesystem                Avail/Total    Files      Status

/LIH1/var/log  (OMVS.I17RS1.LIH1.VARL)   22866/149760   4294967242 Available
