Our environment is: Windows Server 2003, Service Pack 2 SQL Server Express 2005 SQLServer JDBC driver 1.2 (also tried Jtds) Sun JDK 1.6 (we tried this on JDK 1.5 as well) There is no virus protection software on the host, and no firewall is enabled.

We have Web application deployed in JBOSS 4.0.2. Our problem is that the JDBC connection to SQL server periodically gets disconnected, and then we can't reconnect to the SQL server at all, unless we physically restart the server on which JBOSS deployed.

we are getting following error in log.

Software caused connect on abort: recv failed

Note: We are able to connect to SQL server using sample java test class.

Any suggestions would be most appreciated, as this is a serious, mission-criticial problem for us right now.

SQL Server is installed on the same machine running JBoss, or are they different machines? – Evan Anderson Aug 23 '11 at 17:14
