And what's worse, the ulimit setting is not per-process, but per-user. So with Firefox already using 931 of them, your other processes have only 69 left. I built a custom kernel just to increase the maximum. I think -current makes this a bit easier but for 9.x you need a small change in /src/sys/sys/lwp.h: #define MAXLWP 8192 The kernel config file is pretty simple, but it seemed somehow uncertain that the MAXLWP setting there is really active every time "lwp.h" is included (hence the patch to it): include "arch/amd64/conf/GENERIC" #ident "MAXLWP8192" options MAXLWP=8192 options MAXUPRC=2048 -Olaf. -- ___ "Buying carbon credits is a bit like a serial killer paying someone else to \X/ have kids to make his activity cost neutral." -The BOFH falu.nl@rhialto
