Exceptions while acquiring the lock while refreshing the portal.

While user was trying to raise a claim getting this error in Pega SD dispute.
“Exceptions while acquiring the lock while refreshing the portal”

Would anyone please let me know what does this error mean.

@RavinderS16717619 The error message “Exceptions while acquiring the lock while refreshing the portal” indicates a problem with the locking mechanism in Pega. When a user is trying to raise a claim, the system attempts to acquire a lock on the case to prevent other users from modifying it at the same time. If there is an exception during this process, it means that the system was unable to acquire the lock. This could be due to a variety of reasons, such as a conflict with another user trying to acquire the lock at the same time, or a problem with the database. The error could also occur if the user tries to refresh the portal while the system is still trying to acquire the lock.
