Mysql unable to restart problably after disablerepo

[Fabrizio Bartolomucci]

In order to support English coordinates I have made quite a few installations here detailed, but I do not know if that is the reason for the problem.
813 sudo yum install perl-CPANPLUS
814 sudo yum --disablerepo=zeroc-ice install perl-CPANPLUS
816 sudo yum install perl-JSON
819 sudo cpanp -i Geo::Coordinates::OSTN02
820 sudo cpanp -i Geo::Coordinates::OSGB
821 sudo cpanp -i Geo::Coordinates::OSTN02
At any rate, when I tried to restart the mysql server on my centos server after rising the connection numbers, it fails to do so. Actually previously it ran without even a my.cnf file. I tried both without and within but still it does not start not gives errors.
The only weird issue when I execute mysql is that it outputs error:
mysql: relocation error: mysql: symbol strmov, version libmysqlclient_16 not defined in file libmysqlclient.so.16 with link time reference

Could someone please help? This server is in productions and my users are not presently allowed to use it.
