Hi,
i'm quite new to fedora ds,, recently i have been trying fedora ds with
the Jamm schema, it worked fine for like half an hour then whenever i try
to start  fedora ds i get a segmentation fault error as follows

slapd-servername/./start-slapd: line 33: 2526 Segmentation fault
./ns-slapd -D /opt/fedora-ds/slapd-servername -i
/opt/fedora-ds/slapd-servername/logs/pid -w $STARTPIDFILE "$@"

i was wondering if anybody knows whats going on
