Yuan, I've not seen that particular failure before, but some quick research indicates that gconv-modules.cache is a part of glibc and I suspect that it is getting mapped in much the same way as the NCSD file is. I will continue to look into the problem to see what BLCR might be able to do differently, -Paul Yuan Wan wrote: > > Hi Paul, > > Thanks for replying. > The error messege I got from /var/log/messeges is as the following: > > vmadump: mmap failed: /usr/lib64/gconv/gconv-modules.cache > thaw_threads returned error, aborting. -13 > > The failure seems not caused by NSCD.
