Valgrind for Kontact

[daipengg at gurka ~]$ valgrind kontact
==46753==
==46753==     Valgrind's memory management: out of memory:
==46753==        newSuperblock's request for 4194304 bytes failed.
==46753==        69898240 bytes have already been allocated.
==46753==     Valgrind cannot continue.  Sorry.
==46753==
==46753==     There are several possible reasons for this.
==46753==     - You have some kind of memory limit in place.  Look at the
==46753==       output of 'ulimit -a'.  Is there a limit on the size of
==46753==       virtual memory or address space?
==46753==     - You have run out of swap space.
==46753==     - Valgrind has a bug.  If you think this is the case or you are
==46753==     not sure, please let us know and we'll try to fix it.
==46753==     Please note that programs can take substantially more memory than
==46753==     normal when running under Valgrind tools, eg. up to twice or
==46753==     more, depending on the tool.  On a 64-bit machine, Valgrind
==46753==     should be able to make use of up 32GB memory.  On a 32-bit
==46753==     machine, Valgrind should be able to use all the memory available
==46753==     to a single process, up to 4GB if that's how you have your
==46753==     kernel configured.  Most 32-bit Linux setups allow a maximum of
==46753==     3GB per process.
==46753==
==46753==     Whatever the reason, Valgrind cannot continue.  Sorry.
