The following error occurs in the SERVER LOG when a document is placed in a QUEUE:

[SYSREQ_A] 09/01/26 08:17:16 : ! ERR/LOST_DB_CONNECTION -- Collection was modified; enumeration operation may not execute. Stack==> at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)

The error results in the document not being placed in the QUEUE.
