[Raghu GS <raghugs gmail com>]

Hello Everybody

i installed Beagle 0.20 in SUSE 10 from ULB Gnome rpms,
it is work fine, but not for a long time,
actually, 
file system backend is always working.
but IndexingService backend,
KMail backend and Kopete back all are stops indexing after some time,
they indexes unindexed contents only after restarting beagle deamon,
then indexes for some time and then those would stops indexing again and 
those would index only after restarting beagled,

so finally i need to restart beagled frequently to keep beagle 
indexes up-to date,

please help
