Created attachment 195331 [details] -g -ggdb output I recompiled sysstat with "-g -gdb" - probably sth more info now in the output. FWIW it happens after wakeup from hibernation - AFAIC it always happens if a sysgtem was hibernated at least one time before.

I get the same error with sysstat-9.0.3-r1 (have tried 9.0.2 also) and it seems that I got it since I've upgraded to glibc 2.9_p20081201-r2, kernel 2.6.30-r2 and GCC 4.3.2. Runs on a server so no hibernation here (see emerge --info output below). I've tried to get some output from gdb but it doesn't work for me (followed instructions from http://www.gentoo.org/proj/en/qa/backtraces.xml ): wien:~ # gdb /usr/lib64/sa/sa1 GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Created attachment 197156 [details] version 9.0.4 I'm running 9.0.4 (got from the author) since 21th of June here w/o problems.
Ah.. I can confirm that this version works for me too. Thanks!
9.0.4 has been released now and is in the tree. Thanks everyone!
