_wp_session SQL errors in wp_options

[KovaZg]

Hello,
I have wordpress website that is long time up and has many visits.
Issue started not so long ago, when wp_options started to fill in with _wp_session_% and wp session expire in wp_options table.

error_log is rising pretty fast and database filled with 180.000 session entries.

I’m not sure with what is this issue related, I tried plugin by plugin to disable it.

Can you try to help me out, any solution to this, how to find out?

Error log og says:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘_trackPageview’])’,’_wp_session_9a24fadbd1f4dde01afh([‘_trackPageview’])’,’_wp_s’ at line 1 for request DELETE FROM wp_options WHERE option_name IN
and after huge session list …
do_action_ref_array, call_user_func_array, wp_session_cleanup

I tried google for trackPageview, but not sure what is that?
Thank you very much
