I don't get segfaults from vchkpw anymore (not since raising my softlimit), but I get from 1-3 segfaults from qmailmrtg daily. I don't really need or want qmailmrtg, so if anyone can tell me how to turn it off, that would be great. :) Otherwise, it's not causing any problems for me since I don't use it.

While I continue to push that: is there any way to know what process chain is invoking the vchkpw process that’s segfaulting? Don’t a number of different processes use it? I don’t know for a fact that submission is the one that’s causing it. I can’t find any other clues in my logs, like events happening at the same time as the segfaults, but are there any other possible culprits that might invoke vchkpw without enough RAM to do whatever it’s trying to do? -- Steve Linberg, Chief Goblin Silicon Goblin Technologies http://silicongoblin.com Be kind.
