Problem:

While trying to start adclient, you get the error "/var/run/adclient.pid" is not running, similar to the error below: 

root@oseh502a:/var/run $ /sbin/init.d/centrifydc start
Starting Centrify DirectControl: OK
root@oseh502a:/var/run $ psg adlient
root@oseh502a:/var/run $ /sbin/init.d/centrifydc start
Starting Centrify DirectControl: Warning: Pid 9729 in
"/var/run/adclient.pid" is not running.
OK


Cause:

One of the reasons when you see this error may be due to the dc.cache file reaching maximum disk space limit on the machine.


Resolution:

Adclient will automatically flush the cache to recover disk space once the remaining free space limit specified in centrifydc.conf is reached. The cache size can be reduced proactively by running "adcache --reorg" as a cron job on a weekly or bi-weekly basis.

The function will reorganize and clear Centrify DirectControl cache and index files and to reclaim disk space.
