Re: swapinfo
Re: swapinfo
reserve is the amount of space that has been reserved by processes. This is what COULD be needed if you start running short of physical memory.

"reserve
Paging space on reserve. This is the amount of paging space that could be needed by processes that are currently running, but that has not yet been allocated from one of the above paging areas."

Re: swapinfo

The number is reported as a negative value. Think of this as subtracting the reserved memory used from a starting value of zero (reserved).
> any serious memory issue?
That's not possible to intelligently comment until you post the whole output of 'swapinfo -tam'.

Re: swapinfo
Re: swapinfo
Right. This value should be logically subtracted from the FREE value under dev.

Re: swapinfo
Re: swapinfo
The reserve space in swapinfo shows the memory pages . the - symbol is due to as substracting the reserved memory. This is not a serious memory issue.Check with 'swapinfo -tam' out put . First Read manual page for swapinfo.
Hope this help you in single extend.

Solution>>reserve - 9289 -9289
9289 which is the amount of paging space that could be needed by processes that are currently running, but that has not yet been allocated from one of the above paging areas.
swapinfo prints information about device and file system paging space. (Note: the term `swap' refers to an obsolete implementation of virtual memory; HP-UX actually implements virtual memory by way of paging rather than swapping. This command and others retain names derived from `swap' for historical reasons.)
reserve
Paging space on reserve. This is the amount of paging space that could be needed by processes that are currently running, but that has not yet been allocated from one of the above paging areas.
Check below link for details.

If it helps , pls assign point.

Re: swapinfo
Re: swapinfo
By running
swapinfo -ta
you will get the total amount of swap space being used. If the total
percentage used is high, roughly 90% or greater, then you probably need
to add more swap space if its not so i think your system is working with adequate swap space.
But for "reserve" i think the information above given by the experts had cleared your doubts :)
