ayc868 ,

Sorry that you are seeing this issue with MyEclipse.

Can you answer some more questions for us to understand the issue better ?

1) Can you share the Build ID from Help > About MyEclipse Enterprise Edition > Build ID ? Also share your Operating System and version details.

2) Are you deploying your application to Tomcat ? If yes then which version of Tomcat.

3) When exactly are you seeing this issue? Is it during a database operation? Please elaborate.

4) Try putting -vmargs -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M in myeclipse.ini file located at [MyEclipse installation dir]. Check if the issue persists. If the issue is still seen, then change the -XX:MaxPermSize to 256m.

Let us know how it works for you.
