Hello all,
I have create a new package for jxta-c. when I tested this package (installed on usb) I have received a segmentation fault. The application starts well and prints 3 greeting lines and then break down. I have noticed that
the application needs 85Mb of ram on normal PC because Jxta-c cretaes many threads.
My router is AsusWL-500Gd V that run whiterussian_rc5. this router has 32Mb.
My qustions, does this limited memory create a Segmentation fault?
if yes, Can I extend my memory to 128Mb?
is there any way to debug this application?

in the following is the strace output.

I have create swap partion of 128 on my usb2 stick. but it realy fail again and a segmentation fault rised again.
It would be nice whwn you give me any useful idea.

To create swap partition you need swap-util (http://downloads.openwrt.org/backports/ … mipsel.ipk)
run the following command
mkswap -c -v0 /dev/scsi/host0/bus0/target0/lun0/part1
swapon /dev/scsi/host0/bus0/target0/lun0/part1

Hallo,
Is it possible to anyone to install jxta application and tell me what to do with this segmentation fault. It seems that creating swap partition doesn't solve the problem. the problem is really with SIGSEGV.
Is there any way to debug the application or to know where the problem is?
Can any libraray, for example libsqilte3 or libapr rise this problem?
