When my client tries to go to his panel for plesk, below error messages are showing.

Nov 17 22:51:15 plesk kernel: [32302483.436795] sw-engine-fpm[12134]: segfault at 10060 ip 00007f66eb8483dd sp 00007fff4a16f160 error 4 in libmyodbc.so[7f66eb819000+3c000]

When i login (as admin) i do not get these messages. He cannot log in. This is i believe also due to that he has php-fpm for some sites enabled too.

I can see on http://talk.plesk.com/threads/plesk-11-5-inoperable-after-update-to-mu-41-urgent.301273/ pretty much the exact same issue but no steps on how to resolve it as server maintainer. When i want to downgrade to 5.5 it will just remove all plesk packages too. I also seem to have this dotdeb packages in my sources list.

Tried all the tricks that was causing issues, like disabled apc, upping server limits and such but no luck.
I see /usr/lib/x86_64-linux-gnu/odbc/libmyodbc.so, which is normal as i compare it to a box still running 5.5 mysql and plesk 11 but i cant seem to see what now exactly the source of the problem is. I tried to install mariadb at some point but that failed so reverted back to 5.6 from backup.

Any help would be appreciated, its not a killer 'yet' but clients are complaining (sites do work, just not plesk panel)

Hi Erik-janR,

as you can see in the "Software Requirements" - tab at http://download1.parallels.com/Ples...12.0-for-linux-installation-upgrade-info.html , MySQL 5.6 is supported as well with Plesk 12, so there is no need to read issues/problems related to Plesk 11.5.

There are always ways to downgrade system relevant packages, which may cause issues/problems, because non-standard repositories are used, which might be unstable or in testing phases. Please see the man - pages for aptitude and/or apt-get to inform yourself about the usage, relevant additional strings and have a special look to additional strings, which can ignore dependencies. You will have as well the choice to test/simulate your envisaged changes, as well, please see the man - pages to inform yourself about it.

Your informations about your environement are incomplete, we only can guess to make further suggestions, which is quite ineffective and might not be relevant for you.
