Useage of var/opt/BESClient/

(imported topic written by Freemanfb)

We found some AIX servers have a problem that the TEM agent created a lot of files,which made the /var reach 90% utilization.For example,in a server,
/var/opt/BESClient/__BESData/CustomSite_Server_Inventory/__Local/__resultmp_1792
is about 2.14Gbytes.There will be no free space of /var and cause the system not stable.So i want to know if this files is necessary or i can delete them and will not misdelete any useful files.Thanks a lot.
