Is there a mechanism to clear the teiid-buffer periodically in JDV

Issue

[root@jdvapp2 log]# du -hs /var/cache/jbossas/standalone/teiid-buffer/buffer/
9.4G    /var/cache/jbossas/standalone/teiid-buffer/buffer/

[root@jdvapp2 log]# free -g
             total       used       free     shared    buffers     cached
Mem:            63         62          0          0          0          7
-/+ buffers/cache:         54          8
Swap:            0          0          0

In this scenario, we saw the queries failing with null session errors, but when we tried clearing the teiid-buffer memory in the JDV  as below:

[root@jdvapp2 standalone]# du -hs /var/cache/jbossas/standalone/teiid-buffer/
1.1M    /var/cache/jbossas/standalone/teiid-buffer/

[root@jdvapp2 standalone]# free -g
             total       used       free     shared    buffers     cached
Mem:            62         55          7          0          0          1
-/+ buffers/cache:         54          8
Swap:            0          0          0

• The queries ran successfully, let us know whether there is way, we can clear the teiid-buffer periodically in JDV
