Hi, Christoph, Meir and Prashantha all recently encountered Valgrind dying with this message: VG_(get_memory_from_mmap): newSuperblock's request for N bytes failed. VG_(get_memory_from_mmap): M bytes already allocated. with various values for N and M. I've just committed some code to print more information when this happens. If you three are still having this problem, can you try the latest code in the repository (see http://www.valgrind.org/devel/cvs_svn.html) and send the results? That might make it more obvious what it happening. Thanks. Nick |

I looked at the attached vg.log.20643 but couldn't see anything obviously wrong. > VG_(get_memory_from_mmap): newSuperblock's request for N bytes failed. > VG_(get_memory_from_mmap): M bytes already allocated. > > with various values for N and M. What were N and M when it failed? (I can't find the original message right now). J |

Right at the top: VG_(get_memory_from_mmap): sectors[sno].tc's request for 9217920 bytes failed. VG_(get_memory_from_mmap): 231183424 bytes already allocated. The rest of the info is the segment list at the time of failure. >> VG_(get_memory_from_mmap): newSuperblock's request for N bytes failed. >> VG_(get_memory_from_mmap): M bytes already allocated. >> >> with various values for N and M. > > What were N and M when it failed? (I can't find the original > message right now). The sizes from the original emails were: - Christoph Bartosch: 2MB, 242MB - Meir Yeshurun: 1MB, 224MB - Prashantha A.S: 6MB, 39MB Those three were failures in newSuperblock(); interestingly Christoph's new logfile shows a failure in sectors[sno].tc.
