Problems reported while synchronizing CVS Workspace. 0 of 1 resources were synchronized.I was scratching my head for sometime and searched Internet for an answer, but none seemed to be appropriate for my case. Then when I tried to do the check out from command line using plink, I got a message from my CVS server stating that my password had expired and I needed to change my password. So I changed my password and everything started working fine.
An error occurred synchronizing /abcd: I/O exception occurred: java.io.IOException: channel is broken
I/O exception occurred: java.io.IOException: channel is broken
java.io.IOException: channel is broken
If you get the error message above, one possible and easy to check root causes is your password expiry.
