+          <p>[agent] Repeated vacm table dumping fails due to file name 
+	  conflict. When dumping the vacm table to disk, a temoporary 
+	  file with a fixed name was used. If the table dumping 
+	  (snmpa_vacm:dump_table/0) was initiated from several different 
+	  processes in rapid succesion, the dumping could fail because the 
+	  different processes was simultaniously trying to write to the 
+	  same file. This problem has been eliminated by creating a unique 
+	  name for the temporary file. </p>
