What does this error mean (Can't create TCP/IP socket (24))?
- by user105196
I have web server with OS RHEL 6.2 and Mysql 5.5.23 on another server and the web server can read from Mysql server without problem, but some time I got this error:
[Sun Sep 23 06:13:07 2012] [error] [client XXXXX] DBI connect('XXXX:192.168.1.2:3306','XXX',...) failed: Can't create TCP/IP socket (24) at /var/www/html/file.pm line 199.
my question :
What does this error mean (Can't create TCP/IP socket (24))? is it OS error or Mysql error ?
