[GE users] SEGFAULT on sge_qmaster 6.0u1

After restarting, the qmaster daemon fails to start (lx24-x86) - actually it
forks and then fails.


AFAIK I haven't changed anything significant on the configuration (Admin
email address, complexes, load-sensor) within the last while that should
affect sge_qmaster.  Some time ago I did have a problem with spaces within a
complex string preventing the files from being re-read, but I've since
removed the problem.
 
The message file displays the following:

04/22/2005 11:48:47|qmaster|dealog01|W|local configuration
dealog01.zeunastaerker.de not defined - using global configuration
04/22/2005 11:48:48|qmaster|dealog01|I|read job database with 5 entries in 0
seconds


using debug level 'dl 1' I receive the following info:

   889  10995 16384     TSTSOS: 1 slots used (limit 1) -> suspended

   894  10995 16384     te_add_event: (t:5 w:1114163876 m:1 s:(null))
Segmentation fault

With debug level 'dl 2' I receive the following info:


  7228  11006 16384 <-- te_add_event()
../daemons/qmaster/sge_qmaster_timed_event.c 345 }
  7229  11006 16384 --> te_free_event() {
  7230  11006 16384 <-- te_free_event()
../daemons/qmaster/sge_qmaster_timed_event.c 259 }
  7231  11006 16384 --> signal_slave_jobs_in_queue() {
Segmentation fault


Based on these messages, where should I start looking for sorting out the
problem.
