Hey All,
Hopefully someone has run into this, I've done some searching and I can't find this anywhere.
I've gotten eggdrop 1.6.21 to run MegaHAL 3.5, and it runs for a little while, does some brain saves and if I kill the bot to restart it, upon start up it fails with this error trying to load the megahal.brn file:

the only way to get it to start back up is by deleting the megahal brain file and let it create a new one, rinse repeat with the same issue later...
What I've done:
I configured eggdrop from source with TCL8.4. I see no buffer errors or warnings in the compile, the compile finishes fine.
I've edited the mem.c file and increased the memtblsize to 300000, recompiled && make && make install etc.
Running Xubuntu 14.04 64 bit.
EDIT:::
Looks like I fixed it... I started completely from scratch on a CentOS 6 box and the problem has gone away. I think it was a mix of perhaps Xubuntu not acting nicely, or my initial compile / set up was not done correctly which is more likely. |
