Mysql Error 10055
it. The old site was primitive by today's standards. The new site was full of AJAX calls that would refresh elements on the page behind the scenes. However this was bound to put my Database Server under a heavier load than it was used to.After launching the new site everything was going well. But once our members starting loggin in, we started to get this error from all sites on the box.ERROR HY000 MySQLODBC 5.1 DriverCan't connect to MySQL server on 'localhost' (10055) ERROR HY000 MySQLODBC 5.1 DriverCan't connect to MySQL server on 'localhost' (10055)Background on my ServerDual 3.6 Ghz Intel Xeons ( 90 nm )4 x 146GB 15K SAS Drives in RAID 10 on a Dedicated RAID Controller with 256 MB RAM16 GB MemorySoftwareWindows Server 2008 R2SmarterMailSmarterStatsMySQL 5.1Running about 80 Websites.What is the Cause of MySQL Error 10055?The truth is this is more of an Operating System Error than a MySQL error. Each time your website runs a query you open a connection to the Database, run the query, then close the connection. Each time this happens your Server allocates a dynamic port for use by MySQL and your Website. For Websites like mine which may run 2000+ Queries per second, this means that 2000+ dynamic ports must be set asside for these connections. Sometimes your server gets under load and the operating system can't recycle these ports fast enough, leading you to run out of ports and then your server throws a 10055 Error. By default Windows Server 2008 R2 has 16838 Ports designated for Dynamic use. The default ranges are 49152 - 65535. However this can be extended to a wider range of ports.How to Fix MySQL Error 10055To fix the problem you need to increase the number of dynamic ports.Running the following Commands will give give you 50000 ports for dynamic use.On Windows Server 2008 R2Open command PromptType the followingnetsh int ipv4 set dynamicport tcp start=10000 num=50000Press EnterType the followingnetsh int ipv4 set dynamicport udp start=10000 num=50000Press EnterType the followingnetsh int ipv6 set dynamicport tcp start=10000 num=50000Press EnterType the followingnetsh int ipv6 set dynamicport udp start=10000 num=50000Press EnterConclusionEvery Since running these commands, I haven't had a single instance of MySQL 10055 Errors.Hope this helps others with similar problems.Permalink4622 Visitors8599 ViewsTweet Categories associated with How to Fix MySQL Error 10055WebsitesProgrammingASP.NETMySQL Discussion Shahzad Khan | Dec 6, 2015 8:10 AMHi, Thanks for sharing this article, you saved me from a big trouble and actualling bringing up my server without silly re-installations and setups.

" ' need to OPEN the object first! ' or conn.close conn.execute "EXEC ... " ' can't execute after it's closed! %> This can also happen if you are using ADODB.Recordset, and you use open and try to iterate through the results, which are actually EOF. ADODB.Recordset doesn't always die gracefully, and we recommend you stick to more straightforward methods for opening recordsets in ASP. 0 LVL 12 Overall: Level 12 MySQL Server 5 Message Assisted Solution by:str_kani2005-10-01 >>> i'm getting ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on 'localhost' (10055) this can arise when the server is not running... the server may be stopped by your security softwares (if you are running on xp and giving a huge task to MySQL that may need to run a long time using maximum resource) xp will close tasks like this..
