Ack not working properly Xymon 4.3.0.0 beta2 - upgrade?
Hello,
Acks are not working for me, typically when Ack'ing 2 of the same things in a short space of time. But also randomly, Acking stops working.
I have the 'cookie not found, dropping ack' appearing in hobbitd.log but I am not sure if this is a result of the Ack module 'crashing' or a direct cause. I did see some older messages about this and mention of a fix but I combed through all the release notes for all versions and patches since 4.3.0 beta 3 until now.
Note I am using an older version of Xymon, 4.3.0.0 beta2 and I was wondering if upgrading would fix this. I have never upgraded Xymon before and I am not sure if it's an easy task or not.
My fix has been to restart hobbit.sh but this is removing some acks so it's no longer an option as we have now moved into intensive Ack usage.
thanks
All I can offer is that upgrades are relatively easy, if you're using RPM's there is almost certainly a newer RPM out there, and that I've never had problems with acknowledgement really -- my first 4.3 was I think 4.3.7.

You definitely need to upgrade. There was a lot of problems with the ack code in the early 4.3 releases, so I am 99.99% sure that it has been fixed in the current versions.

Upgrading from the beta2 release is a bit more work than normal due to the Hobbit->Xymon name change, but there is a document in the 4.3.x source tree that describes what you must do.

Thanks to both of you, I will be put all this into action soon but will need to test and agree with board.
Henrik, would it be possible to get a copy or a link of what is referred to in this post you wrote in 2011 in a thread entitled '[Xymon] Acknowledge issue continues with xymon 4.3.2 ' please? http://lists.xymon.com/pipermail/xymon/2011-April/031292.html

I've come up with a version of xymond.c that eliminates the rbtree code for the cookies. It uses a much less efficient way of looking up the cookies - basically, it will scan through all of the status-log entries that xymond has in memory - but since this only happens when a cookie needs to be renewed, or when xymond receives an ack, it should not put too much extra load on your system. It would be very interesting to hear if this patch on top of 4.3.2 solves the issue; if it does, then I surely know that there is a bug in the rbtree "delete node" code.

I was not able to get the attachment from the thread/mailing list. I would like to see if this helps as I need to use ACKs ASAP and will not be able to upgrade Xymon for a week or two at best and I'm still on 4.3.0-0.beta2 as described.
thanks

You should be able to download it via the link in that archive mail: http://lists.xymon.com/pipermail/xymon/attachments/20110407/d8b2f9fd/attachm...
I am not sure that will solve the problem for you, as I recall there were several issues that took a couple of iterations before everything worked OK. But feel free to try it.
Regards, Henrik
