How to limit growth of vcenter inventory database in vcenter server appliance?

Hi,

We are using vcenter server appliance 5.5.0.20500 Build 2646489 with embedded postgres database. Recently we noticed that /storage/db containing postgres DB and vcenter inventory database is almost full with vcenter invcentory database occupying plenty of space.

vcenter:/storage/db # df -h .

Filesystem Size  Used Avail Use% Mounted on

/dev/sdb3 60G   53G  3.3G 95% /storage/db

vcenter:/storage/db # du -sch *

34G inventoryservice

396K    journal

16K     lost+found

1. 8.0K    sms
2. 1.2M vmware-vmdir

20G     vpostgres

53G     total

We are fine with postgres occupying 20GB of space. Is there any way we can limit "inventoryservice" size? How do we estimate how much size "inventoryservice" database will occupy?

Thanks,
