[06:30] ercxy: it depends how big you want the stack size [06:31] also.. check the user enviromnet with ulimit [06:32] not more than 64Mb [06:33] :~$ ulimit [06:33] unlimited [06:33] the stack is big enough for that [06:34] the "unlimited" kernel limit is 2GB on i386 === horms is now known as hormseat [06:34] what is the problem you have exactly? [06:35] i wrote a code which does some recursive function calls [06:36] and? [06:36] it works without problem when the matrix size is smaller than 300 [06:36] if I increase matrix size above 300 [06:36] it gets killed immeditaely [06:37] killed how? [06:37] number of recursive fucntion calls are increases with matrix size [06:37] segfault [06:38] is there anything in dmesg after the segfault? [06:38] like a kernel message telling you that it has been killed for some reasons? [06:38] not checked .. iwiil doit right now [06:38] i checked with valgrind [06:40] that's mostlikely a bug in your code [06:40] either it's leaking memory [06:40] or you are trying to access a wrong segment of ram [06:42] i don't do dynamic memory allocation.. is it still possible to have memory leaks [06:43] i mean i defined one global array and do all stuff on it [06:43] are you calculating the amount of ram properly? [06:43] did you check with a strace where the code dies? [06:44] yes.. i checkhed ram usage from "top".. it is never reached above %50 [06:44] did you compile it with -g and run gdb on it? [06:44] top is not fast enough [06:44] no did no tuse strace [06:45] tried gdb and vlagrind [06:45] the program stops random places [06:45] it really depends what you are doing [06:45] i seriously doubt it is a kernel problem [06:46] ok .. it is abt confuding for me [06:47] as far as i know [06:47] ? [06:47] there is one limit set for kernel [06:47] like 64mb [06:47] nope... [06:47] and there is default size 8mb [06:47] that's something you control via ulimit [06:47] for a process [06:48] stack size (kbytes, -s) 8192 [06:48] ulimit -a [06:48] set that one [06:48] do i need to be root [06:48] no [06:48] it's per user [06:48] ok thanks trying [06:51] ulimit -a tells me it = stack size (kbytes, -s) 8192 [06:51] but segfaults [06:51] yes.. increase that value [06:51] you can change it [06:52] how [06:52] man ulimit [06:53] you cant increase it if your a user but [06:53] i tried that, [06:53] it gave error [06:53] You can only decrease it (because obviously if it was set by a login profile you coudl just override it if you want up) [06:54] standard input>:15: realpath on `bash.1' failed: No such file or directory [06:54] BASH_BUILTINS(1) BASH_BUILTINS(1) [06:54] i found man page on google [06:54] reading [06:55] it's somewhere in /etc that you can set the system default [06:55] in any case this is offtopic here [06:55] ok.. thanks.. where should i ask this [06:55] #ubuntu [06:56] i will try there === hormseat is now known as horms [07:45] dpatch-edit-patch: * Applying current external_usagi.dpatch for editing. === ercxy [~ercxy@209-6-112-210.c3-0.wth-ubr1.sbo-wth.ma.cable.rcn.com] has left #ubuntu-kernel ["Kopete] [08:14] http://www.big-boys.com/pictures/picture1009.html [08:14] lol === JaneW [~JaneW@wbs-146-176-233.telkomadsl.co.za] has joined #ubuntu-kernel === svenl [~luther@AStrasbourg-251-1-58-57.w82-126.abo.wanadoo.fr] has joined #ubuntu-kernel === Seveas [~seveas@seveas.demon.nl] has joined #ubuntu-kernel [08:56] Mithrandir, smurfix: ping?

[09:11] if we need to break the kernel, it needs to be asap [09:12] I haven't gotten around to mailing him; been looking for him on IRC for a while [09:14] I'm inclined to just go ahead with xen for the time being. [09:14] but didn't we agree not to break the normal kernel for it? [09:15] Mithrandir: yes, for the beginning, but if it needs to be a standard feature we can't wait too long [09:17] sure [09:18] fabbione: Any news on the xen/L4 virtualization stuff you explored in Sydney? (I can't remember that project's name at the moment :-/ ) [09:18] smurfix: that's the project you 2 are supposed to track :) [09:18] smurfix: afterburning.
