Hi list,

the memory leak is there again, and now I'm trying to use valgrind, but 
without success. 8(
The problem seems to be, that I cannot make sge_schedd to end without 
killing it using SIGKILL (kill -9 ...), SIGTERM or qconf -ks don't stop 
the scheduler.
And it's eating up to over 3 GB memory on this 4 GB memory system and it 
does not end.

After killing it with "kill -9", I get no more output that

=============================================================

=============================================================

in the valgrind output file, since I am killing valgrind!
Is there a way to stop the scheduler in another way without having to 
kill valgrind ?

If I don't kill it, at some point valgrind ends itself with

=============================================================
Valgrind's memory management: out of memory:
    newSuperblock's request for 1048576 bytes failed.
    5026193408 bytes have already been allocated.
Valgrind cannot continue.  Sorry.
=============================================================

See appended files from 2 valgrind runs.

regards, Richard
