The delay is caused by the user settings project being locked - it looks
like the project files were copied from one virtual machine to another when
this project was locked.
There are two lock files that Mercurial uses:
{projectFolder}.hg\store\lock
{projectFolder}.hg\wlock
Usually both of these are deleted at the end of a command, but sometimes
they are left around and need to be manually deleted.
The user settings project was something we created in Paratext 7.6, but
decided to get rid of in Paratext 8. It’s the last project processed during
send/receive, so errors in it don’t prevent the other projects from being
completed.
The user settings project name is a hash value based on the user name so
usually looks like some random string - in the case of the reported
problem, it is l4Bwgh_BX4. Either of the two files mentioned above that
exist in this project will fix the problem the user is having.
