SocketTimeoutException in checking

After I got the OurofMemory error in my another post, I clicked OK, increased the RTC client heap size to 1024, found the "Share Project" option is no longer available. Since I have no idea about the status, I continue "Check-in and Devlier", after some time, I got another error:

CRJAZ0099I When accessing the URL "https://yyyy.gov.on.ca:9443/ccm/service/com.ibm.team.scm.common.IScmService" the following HTTP error occurred: "java.net.SocketTimeoutException"


When I try again, it give me this:


Local projects are out of sync with your repository workspace. You should proceed with caution. If you proceed, the check-in may revert other changes or fail.

To get in sync, you should Cancel and then either: disconnect and reshare the projects with the unresolved changes. Or create a patch containing the changes, reload the projects (the reload is increamental) and then apply the patch.
