[Dovecot] file descriptor errors
Hi,
I use dovecot 2.2.9 on Gentoo Linux and I get lots of these erors in my log file:
Dec 4 08:53:37 mx dovecot: auth: Error: close failed in file object destructor: Dec 4 08:53:37 mx dovecot: auth: Error: IOError: [Errno 9] Bad file descriptor
What could cause these error messages?
My mailboxes are stored on an ext4 filesystem: /dev/vdb1 on /srv/mail type ext4 (rw,noatime)
doveconf -n:

Hi,
just a short question: I had sent exactly this same email with a wrong email address (not the cr@sys4.de) and unfortunately I was to late deleting it in Mailman. Now I get replies to the c@roessner-network-solutions.com address, which will not succeed at the moment, because of DMARC policy. So if you already sent answers, could you please email it again to the cr@sys4.de mail. Thanks a lot in advance

Just fyi, you missed no answers... sorry I can't help...
Maybe problem with the filesystem? Have you fsck'd it?

I found the problem, but do not know, if my solution is okay. It is the checkpassword script that I wrote in python:
… # Return data to Dovecot try: fd = os.fdopen(dovecot_out, "w") except: sl.syslog(sl.LOG_ERR, "Can not write to FD 4") sys.exit(1) os.write(fd.fileno(), "\tuserdb_uid=%i" "\tuserdb_gid=%i" % (uid, gid)) #os.close(fd.fileno())
try:
os.putenv('USER', username)
os.putenv('HOME', local_part_dir)
except:
sl.syslog(sl.LOG_WARN,
"Can not set environment variables“)…
When it comes to the os.close(fd.fileno()) call dovecot throws an error. So for now, I leave the file descriptor open and wait for the script to terminate. I thought, I would have to close the descriptor after using it, do I?

Dovecot doesn’t throw error, Python does. Dovecot just logs it. If os.write() succeeds for the fd, but os.close() immediately afterwards fails, I have no idea why it would be doing that.

Doesn’t really matter. The process dies immediately anyway.
