Hmmm...
There are no issues I'm aware of with SQL Server - character limits are
huge...
Here are some steps to take in solving your problem:
1. change setClientCookies to "no" to eliminate any cookie confusion
2. Add these lines to application.cfm (or wherever) to delete existing
cookies:
<cfcookie name="cfid" value="" expires="now">
<cfcookie name="cftoken" value="" expires="now">
3. Make absolutely sure that cfClientStorage is mapped to the same central
DB on all machines in the cluster
4. Make certain you haven't accidentally hard-coded any CFIDs or CFTOKENs
into a url string somewhere in your code
