Products

Issue/Introduction

The following error has been noticed in multiple remote task server logs:

Error processing incoming tickle connection. Unable to add socket watcher: Socket closed.

[Altiris.DotNetLib.Sockets.SocketClosedException @ Altiris.DotNetLib]

Environment

ITMS 8.1 RU6 and later

Cause

Known issue. The following have been fixed to address this problem:

• trying to decrypt only 471 bytes in case of larger size, because of sent tickle packet(s) after registration data
• more logging regarding the tickle connection establishment
• IP address check "removed"
• lowered logging level for some errors, caused by current implementation of client registration within TS - actually no impact on client registration]

Resolution

This issue was fixed in ITMS 8.5 RU1 and some of the changes made to resolve this issue were:

• the messages "Unable to identify endpoint" were changed as trace message
• the message  "Not registered endpoint is..." should not be there at all - removed IP address check
• the message "Socket is closed" was changed to be a trace message
