hi,

i have configured lda for qmail & it works fine for some time.
later its stops working with the following error on qmail-send logs
deferral: preline:_fatal:_child_crashed/

on google i found may be caused due to corruption of dovecot.index,
after deletion of dovecot.index file it works fine.

following is dovecot-deliver.log
deliver(mailadmin at xyz): Error: Corrupted header in file 
/home/vpopmail/domains/xyz/A/mailadmin/Maildir/dovecot-uidlist (version = 3)

kindly suggest any patch / configuration changes for this.
