The error while importing the current switch configuration from the database table to an internal switch status buffer can occur if the read enqueue lock requested for consistent reading is rejected due to a parallel change operation on this database table.

It is also possible that an internal problem is preventing the request in the required enqueue lock.

The error situation in this particular case case is described under <runtime parameter>:

(1) A lock collision occurred when requesting enqueue lock <runtime parameter>.
This enqueue lock is currently held by user <runtime parameter> with enqueue owner ID <runtime parameter>.
(2) The enqueue server rejects the enqueue request for enqueue lock <runtime parameter> with the internal error code <runtime parameter>. Check any existing enqueue server entries in the developer trace. Unable to import the current switch configuration from the database to an internal switch status buffer.
