Error description

  • Communications Server for Data Center Deployment, V7
Communications Server for AIX, V6.4
Communications Server for Linux, V6.4
Communications Server for Linux on System z, V6.4
----------------------------------------------------
When a remote API client sends an invalid REGISTER message to
a server, the server may become confused and drop out of the
client/server domain.

Local fix

  • Stop/restart the affected server.

Problem summary

  • The client/server module could receive a malformed message from
a client that would cause the server to overwrite an internal
structure. The sympton is that the server would lose its status
as a working node in a domain. Other servers in the domain would
recognize the server, but the server would not see itself as a
member of the domain. This could cause client sessions to fail
due to the server not having full awareness of the domain
topology.

Problem conclusion

  • Code has been corrected to prevent this error.

Temporary fix
