For a fork, I'd suspect you're out of user processes, though checking other resource limits (generally memory and filehandles) is adviseable. There are hard-compiled limits of 256 user, and 512 system, processes, in the 2.2.x kernels. These limits are raised in the 2.4 kernels, though I don't know the values offhand. The value can be raised, but you have to edit sources to do so at least through 2.2.x -- there is _no_ configuration option for this value. I ran into similar issues with exim, procmail, and spam-filtering software a few weeks ago. I tuned my mail configuration to keep from launching a large number of exim processes and the problem went away. Multi-threaded applications are particularly prone to this issue. Peace. -- Karsten M.
