Odd error when setting perms with unixd_set_proc_mutex_perms()

           Summary: Odd error when setting perms with
                    unixd_set_proc_mutex_perms()
           Product: Apache httpd-2.0
           Version: 2.0.35
          Platform: PC
               URL: http://www.ypass.net
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Platform
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: eric@ypass.net


On my system

Linux devel.atomicservers.com 2.2.19-6.2.1ensim.smp-3.0.4-6 #1 SMP Fri Feb 
1 18:02:30 PST 2002 i686 unknown

when the group is set to #-1 in the httpd.conf file, after starting the server, i 
received the following message in my error_log:

[Wed Apr 17 17:33:01 2002] [emerg] (22)Invalid argument: Couldn't set 
permissions on cross-process lock

the call to semctl() in os/unix/unixd.c (line 547) was failing (called by the worker 
mpm module), presumably because -1 is an invalid group?

Setting the group to an existing valid group in the httpd.conf fixes the problem.

Catching this condition and reporting a more friendly error would help other 
people. :)

thanks!
