## Symptoms

- * UserCheck Portal may freeze or stop responding while Security Gateway is under load.
* Restarting UserCheck Portal (e.g. *# mpclient restart UserCheck*) resolves the issue temporary.
* Issue happens periodically on high load environments.
* Rule base includes rules with UserCheck action (Block/Inform/Ask) that are frequently used (have a lot of hits).

## Cause

Soft-lockups of UserCheck are caused by "Local Sync" which is syncing a big amount of data that was generated by UserCheck.

The table grows large once a rule containing UserCheck action is being hit many times in a short period of time.

For example, using a UserCheck action such as Block/Ask/Inform on the cleanup rule for all traffic.
