[SOLVED] mysqld launched by AKONADI eats up >= 2GB of memory

Hello,

Since recently (my system is up-to-date now), akonadi uses an enormous amount of memory on my system.

ps u -C mysqld

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
philipp   2058  1.2 57.2 3373980 2249272 ?     Sl   19:22   0:01 /usr/bin/mysqld --defaults-file=/home/philipp/.local/share/akonadi/mysql.conf --datadir=/home/philipp/.local/share/akonadi/db_data/ --socket=/tmp/akonadi-philipp.qrGhWk/mysql.socket

With only 4GB installed, my system gets more or less unusable.
Stopping akonadi frees the memory, but on restart its memory usage gets as large as before.

Does anyone know what causes this problem/how to fix it?

Thanks in advance,
Philipp

Re: [SOLVED] mysqld launched by AKONADI eats up >= 2GB of memory

Ha, I'm not the only one; my mysqld eats 1,6 to 2 Gbyte Ram; I don't know, when it's happen exactly, because of 8 GByte Ram, I'm still able to work.

Unfortunately it does not happen with a new fresh user :-(
Wrong, it also happens for a fresh new user after start of akonadi; so it's not a configuration problem

I deleted:
~/.config/akonadi*
~/.config/baloo*
~/.config/kaddressbook*
~/.config/kmail*
~/.config/korganizer*

~/.local/share/akonadi*
~/.local/share/korganizer*
~/.local/share/kmail*
~/.local/share/baloo*
~/.local/share/local-mail

/tmp/akonadi*

then I rebooted -> did not help :-(

Any other ideas what could be culprit?

Same problæem here. I have 32 GB but my system from cold boot usually uses 1.2 GB now it uses 3.3 GB. According to top mysqld is eating that extra 2.1 GB.

Re: [SOLVED] mysqld launched by AKONADI eats up >= 2GB of memory

it's jemalloc (what is jemalloc ???)

downgrade:

# pacman -U /var/cache/pacman/pkg/jemalloc-4.2.1-1-x86_64.pkg.tar.xz

solved my problem

Yeah, seems like a major regression was introduced in 4.3.0. 4.3.1 seems to be going out soon...

Yes, that did the trick. I will mark the problem as solved.

It seems that the issue got fixed upstream, jemalloc 4.3.1-1 is working again...
