fbackup: function myalloc could not allocate space

[Kong Kian Chay]

Commd: fbackup -f /dev/rmt/1m -o -v -i /

Error: Function myalloc could not alloc space

*** Attached a file containing
* partial log of errors
* "bdf" output
* "swapinfo -tam" output

Questions :
* How to resolve this problem other than
increasing physical RAM ?
* Is it phy RAM or swapspace out of space ?

NOTE : Incr phy RAM is out as our boss is considering changing the whole system about 1.5 year from now.

Youve overflown a kernel parameter.

Increase the following in /stand/system, rebuild kernel, reboot, and try the backup again;

maxdsiz
maxssiz
maxtsiz

(Make them all really big - as large as physical RAM is ok)

I think you're exceeding some kernel parameters, probably the maxdsiz or maxssiz. maxtsiz is the limit on the text area siz, which is the area in memory where the actual program code resize. This area generaly does not grow throughout the lifetime of the program. Whereas the maxssiz and maxdsiz control the data and stack size of the program, which do grow.

Hope this helps
