Issue ID: 10404 Summary: slapd uses all available memory and starts using swap Product: OpenLDAP Version: 2.6.10 Hardware: x86_64 OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: slapd Assignee: bugs@openldap.org Reporter: tomas.bjorklund@su.se Target Milestone: ---
We have a problem with slapd using more and more memory until in starts using swap. We are using mdb and our maxsize is set to 8192000000. The server has 32GB of ram. data.mdb is around 2.6 GB
Some settings from our slapd.conf: sizelimit 5000 timelimit 600 checkpoint 1024 15 loglevel sync stats
This is how it looks with top: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 314486 root 20 0 31.6g 26.2g 2.6g S 16.3 83.7 8,09 slapd
Depending on the load of the server it usually takes 2 weeks until all memory has been used.
Things that we have tried:
Changed swapiness to 1
Changed slapd service to use this: [Service] Environment="LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libtcmalloc_minimal.so.4" LimitCORE=infinity LimitNOFILE=4096 Restart=on-failure TimeoutStopSec=900
Everything worked fine with bdb and cache settings like: cachesize 100000 idlcachesize 100000
But since switching to mdb we run out of memory.

You have to provide the actual pathname to the executable.

You should repeat this test using a debug build, without stripping symbols. We need the symbol information to get anything useful.

I hope this is better :)

You should repeat this test using a debug build, without stripping symbols. We need the symbol information to get anything useful.
I hope this is better :)
Yes, that's got all the necessary info now thanks. Unfortunately the output doesn't make a lot of sense, it shows all of the leaked memory is actually owned by libsasl2, and it's all traced back to a call from slapd main.c:265 which only occurs once, at startup time. As such any of the memory allocated by that call should only be getting allocated once, not multiple times.
Since BerkeleyDB hasn't been supported in 2.6, what OpenLDAP version were you using previously? And what version of Cyrus SASL have you been using? Can you test again without using SASL or GSSAPI?

Earlier we had version 2.4.44+dfsg-5+deb9u9 I guess since that's the one coming with Debian stretch. So I guess version 2.1.27~101-g0780600+dfsg-3+deb9u2 of libsasl2 too then. Now we are running with Debian Trixie with this versions: slapd: 2.6.10+dfsg-1 libsasl2: 2.1.28+dfsg1-9
It's hard to test this since it only happens on our production system that is under constant load most of the time. This never happens on our test system so I guess it's about connections. I commented out the sasl-host and the authz-regexp from the config and tried some searches on ldap://localhost and this time I got this:

So right now something is using 28GB of anon memory. Tell me if you need some more info.

--- Comment #10 from Howard Chu hyc@openldap.org --- So far it still seems to be either SASL or TLS. But I don't see the same happening over here.
https://bugs.openldap.org/show_bug.cgi?id=10404
--- Comment #11 from Howard Chu hyc@openldap.org --- I take that back. I see that OpenSSL 3.0.13 on my Ubuntu system is leaking memory on every connection, e.g.
Leak, blocks, size: 0x749b7c01aeb0,19,2432 ?? (<unknown_file>:0) stack: libcrypto.so.3 : ?? (<unknown_file>:0) libcrypto.so.3 : ?? (<unknown_file>:0) libcrypto.so.3 : ??

Unfortunately that means this leak must be fixed in the OpenSSL library, not something we can fix here.

--- Comment #12 from tomas.bjorklund@su.se --- Thank you so much Howard for everything. We will head over to openssl and see if there has been some fix in later versions. Or maybe we have to open a issue there also.
Thank you!

Valgrind log with hints that sasl might be the problem.
https://bugs.openldap.org/show_bug.cgi?id=10404
--- Comment #14 from tomas.bjorklund@su.se --- I'm back here. I have been in contact with OpenSSL and they say that it looks like the leak is not from OpenSSL. So I have been using valgrind to check for leaks and it looks like sasl is the culprit. Might be cyrus-sasl that is the problem. Or can it be something in openldap that doesn't remove or close connections properly?
https://bugs.openldap.org/show_bug.cgi?id=10404
--- Comment #15 from Howard Chu hyc@openldap.org --- You're using SASL/GSSAPI? Please rerun valgrind with --keep-debuginfo=yes, otherwise the SASL mech symbols are lost when the modules are unloaded.
It's not necessary to show reachable memory, we only need to look at the blocks that valgrind says are definitely lost.
Which version of Cyrus SASL are you using?
OpenLDAP does all connection setup and teardown correctly according to whatever documented APIs.

This code would appear to be coming from a Debian-specific patch: https://salsa.debian.org/openldap-team/openldap/-/blob/master/debian/patches...
SASL_CB_GETCONFPATH callback contract is undocumented but it does handle global strings so the assumption is that it's the callback's responsibility to manage the lifetime of the returned string *somehow*.
As such this is per-server-init allocation, so not really a meaningful leak.

We have version 2.1.28+dfsg1-9 amd64
We have reinstall the server so it's fresh and should not have any 3rd party patches. I will upload a new log file with only memory that is definitely lost.

It looks like you're using Heimdal, so this is their leak. You'll need full debug symbols to properly trace this. In particular you need to know what the ??? function is here:
==4220== by 0x586C6DC: krb5_get_error_message (in /usr/lib/x86_64-linux-gnu/libkrb5.so.26.0.0) ==4220== by 0x58701E6: ??? (in /usr/lib/x86_64-linux-gnu/libkrb5.so.26.0.0) ==4220== by 0x58724E0: krb5_get_credentials_with_flags (in /usr/lib/x86_64-linux-gnu/libkrb5.so.26.0.0)
