We have 2 servers (environments). One for production (working) and a second recently setup for testing. The transfer seems to have gone smoothly as we can access the master and slaves and the content, etc is displaying. The test Master has both Domain and SubDomain slave sites. After some testing, we found that when resync'ing a slave site that is a SubDomain, the process seems to hang or loop and does not complete. At this point all we can do is stop the page and exit (cancel). This issue does not occur when resync'ing a Domain slave site.

Any ideas of what to check to solve this issue?

In case it helps with troubleshooting, we recently noticed that when resync'ing a Domain slave site, although it appears to process without issue, this is not the case.

Visually the resync process completes and gives the message explaining so. However, as a test I added a module to the Master site. If working correctly I should see the same module created for the slave upon resync'ing. This does not occur.

This is specific to the test environment.

If you require more information just let us know.

Sorry but I don't see like that what could be the difference between your domain and sub-domain that could explain that one is working and the other one is not working.

Perhaps the "hang" is a problem of timeout somewhere that is waiting for something.
Perhaps a problem of DB connection and timeout to connect the DB (this is just an hypothesis)

Perhaps a problem of sharing or connection on another DB that would not be there ????
