VMWARE and EXT3-fs error (device xxx) in ext3_ordered_writepage: Out of memory

condicciones Under high load and memory consumption on linux hosts virtual machines running VMWare, I have encountered the following error:

VMWARE and EXT3-fs error (device xxx) in ext3_ordered_writepage: Out of memory

This occurs when you consume large amounts of RAM (it should swap) and fast (the swap process does not give time to free RAM), and not only is free to that can handle your EXT3 journaling (can not make swap available)

To avoid this, we modify the parameter vm.min_free_kbytes to book, or yes, a certain number of bytes for kernel & company.

To do so, and incidentally, this value is loaded each time the machine boots, add the following line to
/ etc / sysct.conf
(file to set kernel parameters that can be read / changed on the fly)



# Error: EXT3-fs error (device dm-6) in ext3_ordered_writepage: Out of memory per
# Solution deixi prevent vmware no sense l'ext-3 ram per vm

to journaling. min_free_kbytes = 5000




once saved the changes run sysctl

-P

to be reread and apply the settings in / etc / sysctl.conf



The value (5000) is expressed in kilobytes and is the one I've put on my machines, this value is optional but not recommended very high (and 5MB is considered 'very high')

googling I found the solution, which led me to this forum
