On a server running CentOS 6.0 x86_64, Plesk 10.3.1 and the MySQL 5.1.59-1 packages from the atomic channel I get '500 - Internal Server Error' when trying to access the Application Vault page under Tools & Utilities in Plesk.
In /var/log/sw-cp-server/error_log I find:
relocation error: /usr/lib64/libmyodbc5.so: symbol strmov, version libmysqlclient_16 not defined in file libmysqlclient_r.so.16 with link time reference
I found http://serverfault.com/questions/318246 ... nt-r-so-16
about this exact error message which suggests dumping all databases and installing the vendor's MySQL packages.
Apparently the /usr/lib64/libmyodbc5.so file is part of the mysql-connector-odbc package:
# rpm -qf /usr/lib64/libmyodbc5.so
What do you make of this?
