I've had alot of sudden crashes and reboots with eggdrop in the past but this top it all.

I woke up and found that the bot has been rebooting from 4am till 11am every 5 mins. (which is my eggdrop boot script). I haven't changed a thing in my server setup in months except for the mysql server. Which I changed sunday and the errors came up today (tuesday). The everything worked like a charm then so I have no idea why it just started off like this.

The bot seems to have problems getting mysql results but I made the module myself and has been running for months without reboots.

The core file says:

right i just got a clean set of files from eggheads and my module and its working now. just wondering how a bot just cant stay live out of nothing

I'd guess your module somehow corrupts some global mem struct in nonobvious way, resulting in crash on a particular set of circumstances - a nasty bug, but it happens

proceed as usual, gdb the core, post a backtrace

I already removed all the cores and started from scratch. It's all good now.

Same deal again! This time it crashed right after the "WaitForTCL..." command at "clone". I cleaned it, installed a new kernel (2.6.12.3) and tried again. It works now. I will try to remember to post a full bug report here if it happens again. I have a feeling it was a kernel bug tho...

/lib/tls? what's your OS?

recompile Tcl without thread support

Linux 2.6.12.3 // Debian 3.0 Testing.

I didn't compile anything. I just use the apt-get tool to install software that Debian packaged for me.

And the silly thing is. The eggdrop boots perfectly once in a while so i'm guessing that thanks to the add_hook the function that checks the topic of a channel crashes because the channel isnt joined yet when the bot crashes. Could make some sort of failsafe for that but it shouldnt make the bot crash just cause it cant return a channel struct should it?

it is your responsibility to deal with NULL pointers passed to your code - you could complain only if the pointer passed to you is not NULL but points to invalid/corrupt data

give a Tcl lib w/o threads a try anyway - compile from source

I know how to code things Wink

Will try no threads and static debug. As normal debug only provides debug stuff for eggdrop core and not modules. That is as far as the previous debugging messages showed me...

Thanks for the hints.

well that was a short try. it wont join irc when i compile without threads. waited 10 mins. tried 3 times. Neutral

Can't make a static compile as I'm including mysql header and lib files.

We'll have to continue with blinds on then.

tnx anyway.

I am guessing this is a problem with your module. If it is something you wrote and you want some insight on where the problem is in the module, try installing valgrind (google) and run the bot with ./valgrind ./eggdrop eggdrop.conf. valgrid will spit memory errors it finds out to the console (it can also log to a file).

Hope this helps,
Will

Thanks, it found some errors in TLS and TCL. Laughing

So far none in my module. But will test it more, it might just be a small annoying bug.
