Re: [MonetDB-users] MServer crashing: Random Segmentation fault

Could you update your CVS version of pathfinder and try again? If I remember correctly there were some post-release bug fixes to the upward step. (If updating doesn't help could you please report a bug -- if possible with a simplified example query.) Cheers, Jan On 04/18/2008 04:23 PM, jz@uva wrote with possible deletions:

I forgot, output from bt:

You could give us a hint by starting the Mserver in a debugging session:

$ gdb --args Mserver --dbinit='module(pathfinder); mil_start();'

start the Mserver with: run and create a dump as soon as you triggered the segmentation fault with: bt

This should give us an idea where your problem is located.

Thanks, this is the error I am getting:

MonetDB>[New Thread -1319306352 (LWP 18169)]

I hope this helps....
