There are two group files, <tt class="filename">/etc/group</tt> and -<tt class="filename">/etc/logingroup</tt>; the system maps UIDs to numbers using the former, but -initgroups() reads the latter. Most system admins who know the ropes -symlink <tt class="filename">/etc/group</tt> to <tt class="filename">/etc/logingroup</tt> -(hard link doesn't work for reasons too stupid to go into here). initgroups() will complain if one of the -groups you're in in <tt class="filename">/etc/logingroup</tt> has what it considers to be an invalid -ID, which means outside the range <tt class="constant">[0..UID_MAX]</tt>, where <tt class="constant">UID_MAX</tt> is (I think) -60000 currently on HP-UX. This precludes -2 and 65534, the usual <tt class="constant">nobody</tt> -GIDs. -</p><p> -If you encounter this problem, make sure that the programs that are failing -to initgroups() be run as users not in any groups with GIDs outside the -allowed range. -</p><p>This is documented in the HP manual pages under setgroups(2) and passwd(4). -</p><p> -On HPUX you must use gcc or the HP ANSI compiler.

The built in file locking mechanism was -not scalable. Performance would degrade to the point where processes would -get into loops of trying to lock a file. It would try a lock, then fail, -then try again. The lock attempt was failing before the grant was -occurring. So the visible manifestation of this would be a handful of -processes stealing all of the CPU, and when they were trussed they would -be stuck if F_SETLKW64 loops. -</p><p> -Sun released patches for Solaris 2.6, 8, and 9.
