[Dovecot] fdatasync -- Error -- bad file descriptor

[Vijay Rajah]

Hello list,

I have a dovecot 2.2.5 instance configured to use mdbox as mailbox format.
I configured to use separate storage attachments and use SIS.. (doveconf -n
below)

I get this error

Sep  6 12:29:52 vrajah.mydomain.tld dovecot: lmtp(14258, email at mydomain.tld):
Error:
fdatasync(/apps/mail/mailbox/attachments/23/12/2312039008db057a1c75-2efc2d00687d2952b2370000f89409f1)
failed: Bad file descriptor

I'm using centos 6.4 on a KVM with ext4 as fs.

Can someone tell me why i'm getting this error? and how to fix this?

-Thanks in advance
Vijay
