I ran two tests. The first test had the following limits set (bash ulimit -a output) and panicked the system. core file size (blocks) 0 data seg size (kbytes) 22528 file size (blocks) unlimited max locked memory (kbytes) 10240 max memory size (kbytes) 30720 open files 128 pipe size (512 bytes) 1 stack size (kbytes) 8192 cpu time (seconds) unlimited max user processes 128 virtual memory (kbytes) 30720 The second test I used the following: max user processes 32 It exploit application printed "30 processes finished". I am running a 2.2.6-STABLE (980617) system with CAM SCSI patches. I have maxusers set to 10. Following is what I consider relevant sysctl output. kern.maxproc: 180 kern.maxprocperuid: 179 This system is used as my desktop X station, which explains the goofy maxprocperuid value.
