Fixup not running

When I am trying to fixup whole dbs in data folder, fixup task will start and will stop in maximum time of 3 minutes. sometimes it will stop, with out doing anything.

command user : load fixup -f -v

load fixup f -v -Y

load fixup mail -f -v

in all cases fixup just starting and stoping

But same command line is working in other servers. I have replaced the nfixup.exe from anohter server. Still it is not working.

Please help me if anybody can…

Thanks
