Problems after filesystem housekeeping

I have noticed that after I clear up the /var filesystem, there are always problems.

Does deleting the OLDsyslog.log file cause problems like missing directories and problems accessing crontabs?

There were two situations where I faced problems.
1) Deleted OLDsyslog.log (Of course I created an archive of this before deleting).
The next day there were problems of missing directories in a path not even related to the log which is /var/adm/syslog.

2) In this situation, I also did the same - deleted old syslog, and backdated ones, and now there is another problem, whereby users are not able to access their crontab :

Code:
$ crontab -l
crontab: you are not authorized to use cron.  Sorry.
bscs.L28bi02> (/bscsbin/lisa)

And so I checked the server, and found that even the cron directory went missing! So this means that everything under cron like cron.allow was gone. I had to manually create the directory and this file for the user to be able to use it again.

Now the user can list the crontab entries, but not able to save new cron entries :
Code:
/var/tmp/aaaa15475" 277 lines, 14951 characters cron may not be running - call your system administrator

I restarted cron, then I can save the entries.

Also, I realize now that many directories in /var/adm are missing. Like /var/adm/sa, /var/adm/syslog.
I cannot even get any output from the command "last". (To check who deleted the files). The error is :

Code:
# last
 : No such file or directory
