Issue with browsing a SVN 1.9.2, schema 7, packed, repository

["Cotrut, Michael" <Mi...@cbsa-asfc.gc.ca>]

Hi,

We've been using SVN for a couple of years, recently we migrated from 1.7.6 to 1.9.2. We also migrated (dump and load) some of the larger repositories to schema 7 and packed them. 

One of this recently migrated repositories (  SVN 1.9.2 schema 7 repository)  is about 100 GB mostly jar files under tags. About 9000 tags.
When browsing  the root/tags with TortoiseSVN 1.9.2 the operation hangs and causes  the server to recycle after a couple of minutes.  This happens consistently every single time we try to browse the root/tags of the repository. 
We've got same issue when testing SmartSVN.

The same browsing operation was working in 1.7.6, would take a couple of minutes (4-5)  but was working.

Error:
