Summary: Imapd with too many open file descriptors.
Description:
Recieved 226 lines of these in the mail log:
Dec 6 20:50:54 server dbmail/imap4d[6843]: [0x976e6d8] Error:[message]
_set_content_from_stream(+778): opening tmpfile failed: Too many open
files

Possible a leak, or ?
I don't have any debug log for this.

I have uploaded the output of lsof on imapd, and it seems like it's failing
to close some file descriptors.
The count is currently:
[EMAIL PROTECTED]:~# lsof -p 6843 | wc -l
1071

I restarted imapd and it started to leak file descriptors at once during
mail client activity.
So atm I would bump Reproducibility to Always if I could.

Seems to only happen when the client fetches multi part messages

I have made this patch which seems to fix the issue.
I will test this, but as I don't know the code I might have entered the
close() the wrong place, especially the GMime stuff above it makes me a
little uncertain.

Well it didn't, so forget about it.
But I have applied this change:
diff --git a/src/dbmail-message.c b/src/dbmail-message.c
index 203194d..d6ca4a8 100644
--- a/src/dbmail-message.c
+++ b/src/dbmail-message.c
@@ -772,6 +772,8 @@ static int _set_content_from_stream(DbmailMessage
*self, GMimeStream *stream, db
// stream -> bstream (buffer) -> fstream (filter)
-> mstream (in-memory copy)
bstream =
g_mime_stream_buffer_new(stream,GMIME_STREAM_BUFFER_BLOCK_READ);
+
+ assert(!tmp); // Test to make sure that we are not
leaking files.
tmp = tmpfile();
if (! tmp) {
int serr = errno;
And now both imapd and lmptd aborts.
Am I completly off track here, or am I just failing to see the error ?
I'll stop "spamming" you now until I get some feedback :-)
