The Web Service Capture Point does not work on Linux hosts when the number of open client connections is close to or exceeding 1024. On other platforms the limit is set by the OS-level limit of open files for the user (see, for example, the UNIX command "ulimit").

As a workaround, use Interaction Server Proxy as a middleman between Interaction Server and Agent desktop applications.

When a client sends RequestStopProcessing to Interaction Server while the Interaction Server database is unavailable, Interaction Server does not send a request to delete this interaction from the database after the database becomes available again. At the same time in this situation Interaction Server sends EventAck to the client.

If an interaction's binary data size is a multiple of the

Cannot access the database: Too many connections (127.0.0.1)

option value, Interaction Server does not process any operations related to the interaction, including routing, handling by an agent, or viewing of its information. This error appears in the log as follows:

Dbg 27140 No record selected by statement or record does not exist (connection ID: 1)
Std 27013 ODBC error: (connection ID: 1, RC:0, CODE:0, SQLSTATE:'') ''

Workaround: Set a larger value for the blob-chunk-size option.
