## Symptoms

- * Entries in file /etc/resolv.conf are not cleaned up upon user's disconnection in SNX Linux client.

* If the entries are not manually deleted from the file, they pile up, which causes the client to make too many DNS queries.  

  At a certain point, the user is no longer able to connect to the site.

* "Session Parameters" that prints after running command "#snx -u -s" shows DNS suffixes without comma as separator.

## Cause

Bad configuration of the DNS suffixes in SmartConsole, using spaces instead of commas as separators.
