Description Thomas Antony 2005-06-22 11:50:17 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; de-DE; rv:1.7.5) Gecko/20041108 Firefox/1.0

Description of problem:
I am running a mail server with postfix, cyrus-imapd, cyrus-sasl and mysql as backend.
Saslauthd uses with the time more and more memory until there is no swap space available and i run into huge troubles. Random daemons like ssh will exit because of not sufficient memory. I have to restart saslauthd on a regular basis to avoid this problem. 

Version-Release number of selected component (if applicable):
cyrus-sasl-2.1.19-3

How reproducible:
Didn't try

Steps to Reproduce:
1. -

Actual Results:  saslauthd use all available memory

Additional info:

I have set "pwcheck_method: saslauthd" in smtpd.conf

There a several posting on the cyrus mailing lists which concerns this bug. I don't know if it has been already been fixed.

Comment 1 Thomas Antony 2005-06-22 12:02:55 UTC
I did a mistake with the release number which is cyrus-sasl-2.1.18-2.2 and not
cyrus-sasl-2.1.19-3!

Comment 2 Thomas Antony 2005-06-29 13:19:12 UTC
Adding FLAGS="-c -n 0" to /etc/sysconfig/saslauthd avoids the problem for me,
but the memory leak is still there.

Comment 3 Juvenal A. Silva Jr. 2005-07-20 22:33:23 UTC
I found the same problem with Red Hat Enterprise Linux ES 3 with package
cyrus-sasl-2.1.15-10.i386.rpm.
I'd like to really solve this problem, not only work-around it. Now I'm testing
the work-around to see if it's really effective.
I'm waiting your answer ASAP

Regards,

Juvenal A. Silva Jr.

Postings to the Cyrus mailing list indicate that this is a memory leak in the
PAM modules that most of us are using via saslauthd.  Would anyone care to
comment on that?

Comment 5 Thomas Antony 2005-11-27 22:11:22 UTC
pam_mysql is causing the memory leaks.
