----------------------------------------
Summary: Hitting 2100 SQLServer query parameter limit with large
connection base
Key: GUACAMOLE-1796
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1796
Project: Guacamole
Issue Type: Bug
Components: guacamole-auth-jdbc-sqlserver
Affects Versions: 1.5.2
Environment: docker
Reporter: Chris Johnson
Attachments: guacamole-client.log
We have a rather large number of connections and after logging in, I'm getting
"An error occurred and this action cannot be completed".
In the Guacamole log I'm getting the following error:
{quote}^### Error querying database. Cause:
com.microsoft.sqlserver.jdbc.SQLServerException: The incoming request has too
many parameters. The server supports a maximum of 2100 parameters. Reduce the
number of parameters and resend the request.^

I believe that there was a similar issue that was fixed in GUACAMOLE-1253 but
for the number of users.
I have attached the log if that helps.
At the moment, the platform is unusable for ourselves.
