    I cannot connect to Caché sometimes,   the error message is 

            [Cache JDBC] Communication link failure: Communication error: Connection reset

what's the problem?

I have restored one database from backup, but when I query from some of tables,   prompt error :

this error remain after restart Caché service

I can skip this error with %nolock in select query.

My question is: 

1. why there were locks after restart service?

2. Can I release/rollback these locks by sql so I can query without %nolock?

    I restored one database on Server B with EXTSELCT^DBREST command from   backup file (this backup file is taken from Server A).  

When I execute select some rows from one table,  it return error like this,

But when I select other rows from same table on Server B, it return correct data.

Why? maybe the backup file corrupted?
