[horde] horde/apache hangs when home directory has greater than 2GB data

[Steven Marzec]

I've noticed that horde/apache hangs when a users home directory 
contains more than 2GB of data. Horde hangs on that particular user's 
login with the httpd/apache process consuming 100% cpu. Users with home 
directories containing less than 2GB of data seem to work fine with horde.

System Details:
Horde Groupware Webmail Edition 1.0.1
RHEL 4 AS (x86_64)
MySQL backend

Any suggestions on resolving this possible issue would be welcome.

Thanks,
Steven
