[Koha] Error when searching other databases using Z3950

[Tom Obrien]

Hi all,

I am struggling with this error.

I installed koha 3.8.2 on debian 6. When i search other databases
using z3950 i get the following error:

Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (111) at
/usr/share/koha/lib/C4/Context.pm line 758.


I have failed to understand since i can manually add biblios using
original cataloguing  to the database.

Ps help
