The FreeRDP message is probably due to some resource leakage, perhaps in FreeRDP, perhaps in some specific aspect of FreeRDP that 1.5.4 started referencing, that causes the resource to leak to the point where it can no longer create connections, particularly TLS/SSL connections. > > So if my host running guacd 1.5.3 has no issues at all but does with guacd > 1.5.4 (without absolutely any other software change), what do you mean by > "underlying system"?

This indicates that the issue isn't guacd itself, but some issue between guacd + FreeRDP and possibly some underlying library (OpenSSL) that is causing the leakage. -Nick
