Apache subversion coredump on large merge (SSLSessionCache)

Just spent some time tracking this one down, so noting here
         in case anyone interested.

         I found my svn tree would sometimes give the following
         error on large merges:

             svn: GET of '...': SSL negotiation failed: Secure connection truncated (https://...)
             svn: Error reading spooled REPORT request response

         A TortoiseSVN svn client would give a similar error.

         - This would *only* on https, never on http or file checkouts.
         - It would never happen on checkouts of the full tree, but
           sometimes on svn update, and more frequently on large merges.
         - If it happened on a merge it would *always* happen on that merge
           (and leave the checked out tree in a mangled state).

         This was tested under apache-2.2.10 and apache-2.2.11nb5
         with subversion-base-1.6.2 and ap22-subversion-1.6.2nb1 on
         a NetBSD i386 5.0 system.

         The "problem" turned out to be an SSLSessionCache directive
         in the apache config. Removing that avoids the issue. Tested
         with shm: and dbm: values to SSLSessionCache.

         So, this could be an apache issue, an svn issue, or just my
         config issue, but on the chance someone else sees something
         similar, I thought it best to have this archived in the lists
         for future searchers :)
