Bug #23826 Lost Connection when running MyISAM and InnoDB simultaneously

Description:
Previously I was only using MyISAM database on my Windows Server 2000 & XP for my .NET applications. That worked fine. Now, I've a couple of databases running on InnoDB as well on the same server. But then, I start getting this "Lost connection to MySQL server during query" error. It ONLY occurs to my .NET application with MyISAM database. Not one of my applications with InnoDB gives this error.

How to repeat:
Run .NET applications that use both MyISAM and InnoDB databases on Windows Server 2000 or XP with multiple users/connections. Initially it'll work fine, but after many connections, it'll start to give the "Lost connection to MySQL server during query" error.

Thank you for a problem report. Please, try to repeat with a newer version, 5.0.27, and inform about the results. What version of Connecotr/Net do you use? Do you have anything strange in MySQL server's error log?

MySQL - 5.0.22-standard-log
under some usage (near 3 queries per second) continually but not always 
get error in mysql_connect (or mysql_pconnect) function

#/*--------20:45 xxx.xxx.xxx.xxx /get.db.php?id=28863------*/
fatal error: connect to DB failed: Lost connection to MySQL server during query 
#/*--------20:45 xxx.xxx.xxx.xxx /get.db.php?id=33419------*/
fatal error: connect to DB failed: Lost connection to MySQL server during query 
#/*--------20:45 xxx.xxx.xxx.xxx /get.db.php?id=35393------*/

#/*--------20:45 xxx.xxx.xxx.xxx /get.db.php?id=24381------*/
