We run Spark 2.7.0_655 with JRE Version 1.7.0_51 across 2 subnets (call them 0 and 1). Clients are on Win 7 x64.
Openfire 3.9.3 is run on Subnet 0, and all clients work well. However, a client on subnet 1 will not show up in the contact lists on subnet 0 until they restart the client. This appears to be unique to this 1 client.
We are not using LDAP.
Any help would be appreciated.
