Thanks Steffen for the valuable knowledge.
Need to know futher that, how could this lead to mails to get re-downloaded. ??
Because Dovecot detects that the UID list is erroreous and therefore
rebuilts it. To prevent data loss, either the complete list of messages or
just the conflicting ones [the messages that had been delivered in
parallel and caused the while problem] do appear as new to the clients.

transaction log file
/indexes//mail/v3store/example.com/14949_kavish/.INBOX/dovecot.index.log took
133 seconds
some process keeps the INBOX locked, but does not touch the file, so it
looks like a stale lock.
Jul 23 15:34:51 popserver dovecot: pop3([email protected]): Error: Broken file
/indexes//mail/v3store/example.com/14949_kavish/.INBOX/dovecot-uidlist line 180:
UIDs not ordered (10156 >= 10156)
Therefore some other process had broken the lock and had appended a
message.
Jul 23 15:35:01 popserver dovecot: pop3([email protected]): Error:
utime(/indexes//mail/v3store/example.com/kavish/.INBOX/dovecot-uidlist.lock)
failed: No such file or directory

utime(/indexes//mail/v3store/example.com/kavish/.INBOX/dovecot-uidlist.lock)
failed: No such file or directory
then the former process(es) finish and try to clean up, but the "some
other process" already deleted the lock file.
Jul 23 15:35:21 popserver dovecot: pop3([email protected]): Warning: Our
dotlock file
/indexes//mail/v3store/example.com/kavish/.INBOX/dovecot-uidlist.lock was
deleted (kept it 30 secs)
---------------------------------------------------------------------------------------------------------------------------------------------------------
So you have to check your system why a process, that as locked INBOX, is
stalled for more than 120min.
