TMM crash and coredump while logging to remote logging server.
TMM runs out of stack and dumps core. Stack trace shows recursion in errdefs. The system cannot function under these conditions. This is an issue that might occur anytime logs are generated when managing resources that are also used by the logging system itself.
The problem might occur when a log message is created as the result of errors that can occur during log-connection establishment. The crash specifically occurs when an error occurs while attempting to connect to the remote logging server.
Two possible workarounds are available: 1) Create a log filter specifically for message-id :1010235: that either discards or directs such messages to local syslogs. 2) If the problem occurs on TMM startup, disable and then re-enable the corresponding log source once the TMM starts up.
TMM no longer crashes and coredumps while logging to remote logging server.
