So, there is a difference in the columns here ... the column with the 'g' is the 'virtual' usage, that means its the amount of RAM allocated for potential usage. Its not using all of that memory right now, but it can under large circumstances change to use that much. I'm not quite sure why this is so high, you'd need to show a full output of your settings, perhaps a ps auxwww | grep java will give us the settings that have been passed and will enable me to understand why its so high. Either way, it's usually been set to do that by someone/something - by default our settings shouldn't enable Java to consume 12 GB out of the box, so I can only presume the heap setting was changed at some point. The column just after that is the RES column, indicating how much its actually consuming now. This is usually the important one. I'm of course trivialising the description of each column, but understand virt versus res is important. There are lots of articles on the internet about this subject that are definitely worth researching as a sysadmin. Another thing, if that is truly that high, you might want to check your dmesg output to make sure the process isn't getting caught by the OOMkiller in Linux. I have no other information about your system then what you've given me, so I can't make a judgement on whether 12 GB is high or not for you. It does seem high, although I could understand this increase in the setting if you were processing a lot of data. ken. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
