Hi folks,

we are running Rsyslog 3.18.x on SLES10 and have stumbled upon a weird phenomenon.

Our client rsyslog sent messages to a central rsyslog using tcp. They are configured to buffer locally if the central is not available.

Now, if the tcp connection does not leave FIN_WAIT1 state (may be the TCP ACK does not reach the client for network reasons) the client rsyslog stops all activity (writing to local logs, importing local logs, etc.) and does not write anything into the queue buffer files. In fact it seems dead until rebooted.

To my understanding this is not the exptected/intended behaviour, so the question is: Is this a known bug of this version? Is there a version that can handle frozen FIN_WAIT1 states (I know they should not appear at all but that is a different issue)?

Any hint to docs and understanding is greatly appreciated.

Dirk
