Even though there is a total of about 76 MB free, all of it is in separate pieces of 64 kB or less. If the driver attempted to allocate a contiguous chunk of 128 kB or more in the DMA32 range, it would have failed.</P><P>&nbsp;</P><P>Since there seems to be plenty of free memory, this would seem to be a memory fragmentation problem. If you have an application that is using a large number of small pieces of memory, stopping and restarting the application once in a while (e.g. weekly/daily) would allow the kernel a chance to coalesce the freed memory into larger chunks again. But that is just a workaround: a better solution would be to change the behaviour of the application. If the application has any memory-related settings that could be adjusted, now might be a good time to review them.</P> Mon, 25 Nov 2013 09:11:17 GMT https://community.hpe.com/t5/operating-system-linux/warning-in-syslog-hpsa-host-scan/m-p/6280499#M54478 Matti_Kurkela 2013-11-25T09:11:17Z Re: Warning in syslog. hpsa-host-scan https://community.hpe.com/t5/operating-system-linux/warning-in-syslog-hpsa-host-scan/m-p/6284501#M54481 <P>Thank you for your answer.</P><P>&nbsp;</P><P>Everything is clear but I still don't know what is it hpsa-host-scan I couldn't find any files called hpsa-host-scan or similar to this name.
