For Windows error 32, that indicates the following "The process cannot access the file because it is being used by another process." They may have eventually be replicated however if you are consistently seeing this on the report, you may want to see what process is locking the folder. It could be AV software or another application. You could use a utility such as Process Explorer to find out more about this. http://sso.forum.commvault.com/forums/24395/ShowThread.aspx
Windows Error 87 indicates the parameter is incorrect. This error can appear occasionally as a false error. The quickest way to check for file failure is to compare the size of the directory on the source and the destination. If the file count and directory size match, then the replication has completed successfully for that directory. You should make sure you have the latest service pack installed on these 2 servers as well as the CommServe.
