markopolo2002 Posted January 27, 2009 Share Posted January 27, 2009 Think this might be one to put through as a ticket for the IPS guys themselves as they would then have complete unrstricted access to the server and it would probably take them no time to work through the issues with that kind of access as opposed to me fumbling through it. I'm just concerned that the longer I let it go the potentially the bigger the problem may get and I've shed bucket loads of blood on the site over the past year and really don't want to leave anything to chance at this stage. If there is something I've maybe overlooked please feel free to suggest it in the meantime. Thanks for all your help so far wondering soul and hopefully I'll have some definate good news to post back shortly :) Cheers Marko Link to comment Share on other sites More sharing options...
Wondering Soul Posted January 27, 2009 Share Posted January 27, 2009 It may be an issue they see a lot so it might be relatively easy to fix! Its got me stumped now though so it would be interesting to hear back from you when they have answered. Im just very curious now lol Link to comment Share on other sites More sharing options...
markopolo2002 Posted January 27, 2009 Share Posted January 27, 2009 Will definately post back with whatever details they are able to offer (hopefully AFTER they fix them :) ) Link to comment Share on other sites More sharing options...
markopolo2002 Posted January 28, 2009 Share Posted January 28, 2009 OK, so the guys at IPS managed to spot that half my tables were InnoDB and they suggested that our server probably wasn't configured properly for InnoDB and that could be the prob. I asked them to do what they felt would clear the issue and lo and behold I saw much better performance as soon as they changed the InnoDB tables back to MyISAM. Personally, I'm not sure why or how it would make a difference but I can definately see a performance increase and our CPU doesn't shoot through the roof anymore!. Next thing I guess it start working on that my.cfg file and for now thanks Wondering Soul for your input and thanks to IPS for their support :) Cheers Marko Link to comment Share on other sites More sharing options...
Wondering Soul Posted January 28, 2009 Share Posted January 28, 2009 Not sure why some of your tables would be set as InnoDB by default, unless you use to use InnoDB of course. Well glad to hear its all sorted out now =] Link to comment Share on other sites More sharing options...
markopolo2002 Posted January 30, 2009 Share Posted January 30, 2009 Just to continue on with my original query ^_^ I'm now noticing a great difference in the site performance although I'm stil getting loads of other errors in the logs such as ... # MySQL server has gone away # Lost connection to MySQL server during query # Lost connection to MySQL server at 'sending authentication information', system error: 32 # Lost connection to MySQL server at 'waiting for initial communication packet', system error: 95 # Lost connection to MySQL server during query # Can't create UNIX socket (12) # User ########_root already has more than 'max_user_connections' active connections As is obvious, these are MySQL issues still and despite having tweaked the my.cfg to death is there anything else I could do to solve these errors? my.cfg[mysqld] skip-bdb log_slow_queries=/var/log/slow-queries.log long_query_time=5 [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock skip-locking #skip-innodb query_cache_limit=4M query_cache_size=128M query_cache_type=1 max_connections=200 max_user_connections=1000 interactive_timeout=120 wait_timeout=120 connect_timeout=120 max_heap_table_size = 64M thread_cache=32 key_buffer=256M join_buffer=1M max_allowed_packet=64M max_connect_errors=1000 table_cache=1800 record_buffer=1M sort_buffer_size=2M read_buffer_size=8M read_rnd_buffer_size=524288 max_connect_errors=10 # Try number of CPU's*2 for thread_concurrency thread_concurrency=8 concurrent_insert = 2 myisam_sort_buffer_size=64M #log-bin server-id=1 [mysqldump] quick max_allowed_packet=16M [mysql] no-auto-rehash #safe-updates [isamchk] key_buffer=64M sort_buffer=64M read_buffer=16M write_buffer=16M [myisamchk] key_buffer=64M sort_buffer=64M read_buffer=16M write_buffer=16M Cheers Marko Link to comment Share on other sites More sharing options...
rct2·com Posted March 2, 2009 Share Posted March 2, 2009 Why has mysql been running for so long in all those top listings? Shouldn't it be dying, then restarted after periods of inactivity? Link to comment Share on other sites More sharing options...
