3.3a authentication hanging

[Jeff_Bartlett]

/*
 *
 *  This program hangs on the second pass through 'shepherdprocess'.
 *  the forked child stops at

 (gdb) where
 #0  0x3bc00 in select ()
 #1  0x2b4e0 in IOMGR ()
 #2  0x2aa20 in Create_Process_Part2 ()
 #3  0x2b228 in savecontext ()
 #4  0x2b980 in IOMGR_Initialize ()
 #5  0x12 in _DYNAMIC ()

 *
 *  software: AFS 3.3a
 *  platform: sun4m_412
 *
 *  Are there other ways to do this without pulling in the LWP package?
 *
 *  Or better yet has anyone made "Generic NQS" AFS aware?
