From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031023 Description of problem: We have upgraded several of our smaller systems to ES 3.0 and during boot they report that 256MB is the minimum supported configuration even though these systems already have 256MB installed. It appears that the redhat-support-check program does not take into account the memory that is allocated to the kernel during boot and thus thinks these systems have marginally less than 256MB. For example on system produces the following message: WARNING: Red Hat Enterprise Linux ES release 3 (Taroon) requires at least 256MB RAM to run as a supported configuration. (248MB detected) and another produces: WARNING: Red Hat Enterprise Linux ES release 3 (Taroon) requires at least 256MB RAM to run as a supported configuration. (249MB detected) However, both systems report the following in dmesg respectively: 255MB LOWMEM available. ... Memory: 252480k/262136k available (1524k kernel code, 7228k reserved, 1086k data, 164k init, 0k highmem) 255MB LOWMEM available. ... Memory: 252228k/261888k available (1524k kernel code, 7228k reserved, 1086k data, 164k init, 0k highmem) So, either the error message is misleading and you need more than 256MB of physical memory (perhaps 256MB + 8MB), or the program should relax it's check to allow for memory that is allocated to the kernel, in either case I think that's a bug. Version-Release number of selected component (if applicable): initscripts-7.31.6.EL-1 How reproducible: Always Steps to Reproduce: 1. Install ES3 on system with exactly 256MB physical RAM 2. Boot system and Warning will be generated 3. You can also run redhat-support-check to generate the Warning Actual Results: The following warning is generated: WARNING: Red Hat Enterprise Linux ES release 3 (Taroon) requires at least 256MB RAM to run as a supported configuration. (248MB detected) Expected Results: If 256MB of physical memory is the actual requirement then there should be no warning on such systems. If >256MB is required then the error message should indicate the actual amount of physical RAM required for a supported configuration. Additional info:
