Re: [Wrapper-user] Very Noisy Logs - "Previous control code"

[Leif M. <lei...@ta...>]

Mark,
I was just going back to give you an update on this issue and realized
that the following mail was still in my drafts..  Sorry about that.

We have added a queue which allows for up to 25 control codes per 10ms
cycle of the Wrapper to be enqueued.  This should be far more than
enough.   This has been implemented for the upcoming 3.5.5 release.
Please give it a try when it comes out.

Cheers,
Leif

Mark,
I did some more investigation of this.   Sorry.  This is a slightly
different problem than what I mentioned the other day.

Starting with version 3.5.1, we reworked the way signal handlers in
general are implemented so they now do as little possible within the
interrupt.   This was needed to avoid very rare deadlocks in logging
code and mallocs.

The problem is that the signal handler now makes a note of the most
recent signal and then the main loop processes it.   As it is written,
if you get more than one service control code per loop of the main
method, you will see a warning like the one you are seeing.

I have made some changes for the next release to make this much more
robust.   In the mean time, if this is a big problem for you, version
3.4.1 may be the best temporary solution as that version has been very
stable as well.

Cheers,
Leif
