[Glass] Error migrating instances

[Sebastian Van Lacke]

Hi all,

I'm getting an error while migrating instances. I have added an instance
variable to a class, and I trying to migrate the instances by evaluating
this code:

| userHist allUsers |
userHist := CSUserRequest classHistory.
allUsers := SystemRepository listInstances: userHist.

1 to: userHist size-1 do: [:index |
 (userHist at: index) migrateInstances:(allUsers at: index) to: (userHist
at: userHist size)].

After some minutes, I get this error:

a Error occurred (error 2501), An operation that needs to acquire the
gcLock was not able to get the lock within a reasonable amount of time.

I have no idea how to proceed. I will appreciate some help.

Thank you very much

Sebastián
