Internal error. pcsStart error (1361 GLJPST1.C)

User gets this error when they attempt to post a GL Batch.  Sage 300 ERP 2012, SQL. 

In addition, over the past couple of days the same user has been getting the following error message "System error. Cannot lock database" when they try to post a Payment Batch.  I've searched the KB but get no results on either of these items.  Anyone have any ideas?

Thank you.
