Package: nscd Version: 2.3.6.ds1-13 Severity: grave Justification: renders package unusable Well, I believe this is somehow important, on all of my servers it crashes in about 15 seconds. Please note that I am using a lot of groups (more than 2000) and that my servers are heavily loaded. I am using a vanilla kernel (without grsec, pax, and such). It worked without problem on Debian Sarge. Here is a gdb output (without symbols however) : # gdb /usr/sbin/nscd GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.

So you have to purge the cache manually, and it /should/ work after that.
