[MonetDB-users] MServer crashing: Random Segmentation fault

Hi all, I am using MD4 with XQuery + PF/Tijah module. I have a problem that my server sometimes/frequently crashes. I could not detect a trigger, as it occurs randomly and at any time. It gives me this error: 26747 Segmentation fault Mserver --dbinit="module(pathfinder);" but it gives me any number before it. I am not sure where I can locate the MD error log (if it exists), and how it is triggered. Help? Thanks, junte
