Still trying to nail this down.
Question: for setups where the mysql server is on a different system
(but still on the local network), what is the recommended setting in
mysqld for 'skip-name-resolve'?
I'm thinking that, if 2.2.5 does use more connections as someone else
said, maybe this problem is being caused by lots of client connections
from outside from clients with poor reverse DNS resolution, because I do
(and always have) seen lots of these kinds of warnings from phone based
clients:
warning: hostname mobile-166-205-065-239.mycingular.net does not resolve
to address 166.205.65.239: Name or service not known
So... maybe granting the required privileges to my sogo server's IP
address, and enabling 'skip-name-resolve' on the mysql server would
resolve this issue?
I have already tried increasing max_connections from 151 (which is what
it was set to before) to 300, but am still having the occasional 'lost
connection' error.
I need to get this resolved, because yesterday evening I actually had my
mysql server start refusing connections from my sogo server with:
ERROR: could not open MySQL4 connection to database 'sogo': Host
'sogo.media-brokers.com' is blocked because of many connection errors;
unblock with 'mysqladmin flush-hosts'
