Out of Memory error while compiling on HP-UX B.11.00

Mrunal Nerpawar — Mon, 07 Mar 2011 10:35:04 GMT

Hi,

While compiling my c++ application on B.11.00, I am getting following error:
Error 6355: Exact position unknown; near ["Files.cpp", line 1244]. # [line 0 Files::FileList()] Out of memory.
Check kernel maxdsiz parameter and swap space configured. (6355)

Files::FileList() is the newly added function and I am getting above error if i add this function to my file.
The file has around 1400 lines (after adding new functions)

output of kmtune for maxdsiz value:

#kmtune | grep maxdsiz
maxdsiz 0x040000000
maxdsiz_64bit 0x0000000040000000

Can anybody help me in resolving this?

What version of the aC++ are you using?

>The file has around 1400 lines

How many lines if you count include files? Compile with "-E -.i" and count lines in the .i file.

You are at 1 Gb, nothing can be done except split up the source or drop the opt level.

This is very old. The last version was A.03.55, 2004

>around 1950 lines in total.

That seems pretty small. What opt level? And do you have enough swapspace when you were compiling?

Please provide "swapinfo -tam". It appears you have under configured your swap and RAM. You need multiple Gb.

>I tried with 01 - 04, nothing worked for me

You could try the default +O0.

With default also, its throwing the same error.

You are likely out of swap while compiling.
You can check by adding at least 1 Gb of swap.
Or monitor the ctcom process in top and see how much memory it is using when it aborts.

This is the state of ctcom when the it is failing:

pts/0 12560 root 232 20 75040K 58656K run 0:14 94.43 49.82 ctcom.pa20

This looks like you are out of swap. Unless the compiler tried to get 1 Gb at the very end.

Hi:

Adding additional, secondary swap is so quick and easy that dancing around Dennis's suggestion to do so maybe wasting time. There are a number of threads showing how to add additional device swap. See for example:
