Ever since I've installed the HP-UX 7.0 X11 on a 9000/370, I've found the swap space slowly disappearing if I keep an X running. After about a week, the system becomes unusable until I kill that X process and start another. This didn't happen with HP-UX 6.5. Is this a known problem, and is there a fix? In that regard, does anyone have an fstat that runs under HP-UX on a 300 series? On a Sun, for example, fstat -s gives one statistics on swap space use. Thanks, Tony Hearn hearn@rand.org

In case anyone was confused by my last message, it's pstat I want, not fstat. Thanks, Tony Hearn hearn@rand.org

Are you using the same clients in the same pattern as before? The nature of Unix malloc() and free() are such that the memory used by a process employing these mechanisms will never shrink. Additionally, we have observed problems wherein the memory pool of the allocator becomes severely fragmented over time, mostly because of foolish use of the allocator on the part of the server. Finally, we have seen genuine leaks in the server, but I don't off hand know of any in the 7.0 server (but wouldn't bet against it). You might want to try the supported R4 server announced here awhile back. It should use somewhat less memory than the 7.0 server, and if you have a 98550A display card it will be substantially faster. Harry Phinney harry@hp-pcd.cv.hp.com
