shmat/Memory issues...

leaddore · #1 06-27-2010, 12:59 AM

Ok, I have been working on this server most of the day, and I am almost there, however now when I try and run world, I get:

as root
shmat failed! Invalid argument
*** buffer overflow detected ***: ./world terminated

as normal user
failed to get 0-length shared mem: Permission denied
shmat failed! Invalid argument

and a really huge stack trace, I have searched the forums and found where to increase the size of my shmat and have done that with no change in the error at all, even with increasing my shmat up to 512000000

However, I have noticed that if I dump the DB completely, the server will run (with what it can run without a DB) up to almost letting a client login, so I am thinking it has something to do with the DB...

I have downloaded the latest source, with the latest DB from projecteq and I am at a loss right now, the logs indicate everything is starting ok, it just seems like it is trying to do too much or something...here is the whole stack trace

Ok, the shmat was not causing the issues, I got that error to go away (who would have thought you have to REBOOT a linux server for that to completely work) but I am still getting a similar crash now, however, it seems to be crashing out when I get to "Loading Adventures" in the log files, it hits that and immediately core dumps, if I dump the DB completely it will run, although not work properly since there is no DB... so I am guessing it has to do with the DB.

Anyone have any good ideas?
