Random Connections to MySQL refused (Error 111)
- by joatis
A Perl/CGI webapp that has been running fine for almost a year has started to randomly been unable to connect to a remotely hosted MySQL. The Error thrown is :
Can't connect to MySQL server on 'xx.x.xxx.xx' (111)
Reloading the page often solves the problem
The client is using Perl, DBI and SSL to connect to MySQL using the same configuration file each time.
MySQL 5.0 Server Running RH EL5
Quad-Core AMD Opteron(tm) Processor 2374 HE, 8 cores
Real Memory: 15.73 GB total, 11.81 GB used
allows networking in my.cnf
max-connections are not being met
load is low.
The servers firewall is open to
the client's subnet.
The mysql user has permissions
from the client's subnet.
I have my host looking into the problem but so far we're all stumped as to way the occasional connection is (increasingly getting refused)
Any advice what to check that would cause the random refusal of connections?
