Hello,

I am running stunnel on Linux in client mode, and I have the following setting in "stunnel.conf":

output=stunnel.log

The log does not get written to periodically while the program is running but is delayed until after I have closed the program. It would be helpful to be able to look at it from time to time, especially while troubleshooting. Any way "to push" the data down into the file sooner? Thanks.

Hi John,

For performance reasons in most cases it is not a good idea to flush log buffers every time a new line is logged. On the other hand, as you mentioned, sometimes it makes sense to see the logs as soon as they are produced.

There are two solutions: 1. I could add a new configuration line option to control logfile buffering. 2. I could add a new thread flushing the logfile buffers every second.
