Out of curiousity, I went and installed Valgrind 1.0.3 (1.0.4 is latest, but I was lazy and used the Debian package and apt-got it). On my dev. AOLserver instance, just starting it up under Valgrind, hitting the server 2 or 3 times, then stopping it, Valgrind generated a slew of errors. Most of

Or in an external database driver. You can set up a driver where the SQL it accepts is whatever you need, and then it returns results in a single column of a single row. This works especially well if you want to set up a pool of them On Thursday, November 7, 2002, at 04:49 AM, Zoran Vasiljevic

As I've mentioned here before, I have a vendor C library, to which I do not have the source, which can corrupt the heap, eventually leading to segfaults. Purify reports the various errors nicely, but there's nothing I can do to fix the code other than reporting the problems to the vendor. What I

I recently tried the Solaris malloc debugging facility, but the AOLserver (running ACS) went from taking about 5 minutes to start up to taking over 72 hours to start up. AOLserver uses so much dynamic memory that any malloc debugging solutions that work by adding virtual-memory hardware guard
