[Crash-utility] crashdc: Memory issues when running in kexec context on SLES11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello (again), I have been able to get <insert your favorite name here> to run on RHEL5, SLES10 and SLES11. RHEL5 runs without any modification to the standard install. SLES10 requires the crashkernel parameter to be increased from 64M to 128M so crash can run correctly. My concern is with SLES11 which requires a non trivial modification of the crashkernel parameter to correctly run. When I use the standard crashkernel parameter, we've seen that crash simply doesn't run. When I increase the reserved memory to 256M as indicated by Bernhard, it runs but I get errors on pipe and some of the commands do not complete. When I use crashkernel=256M-:256M@16M everything works fine and I have no problem with the pipes. I got a "cat /proc/meminfo" executed right after execution of the script on both RHEL and SLES11, but I do not see any evidence of memory limitation. I have /proc/meminfo for all 3 runs if someone wants to have a look. I feel that requiring 256M for crashkernel is a bit large, but I may be wrong. What also puzzles me is the difference b/w SLES10 & SLES11.
