How much RAM and swap do you have?
After mounting my swap partition, here is /proc/meminfo: bash-2.05b# cat /proc/meminfo MemTotal: 149140 kB MemFree: 138824 kB Buffers: 4 kB Cached: 5248 kB SwapCached: 0 kB Active: 4144 kB Inactive: 2168 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 149140 kB LowFree: 138824 kB SwapTotal: 751864 kB SwapFree: 751864 kB Dirty: 0 kB Writeback: 0 kB Mapped: 2624 kB Slab: 6272 kB Committed_AS: 1672 kB PageTables: 120 kB VmallocTotal: 4096 kB VmallocUsed: 440 kB VmallocChunk: 3656 kB Also note, I'm getting errors from kswapd when tic runs out of memory. Sorry, I don't presently have this error to show you. Something along the lines of that it can't allocate from swap.
Ok. Found & fixed. DO NOT TURN ON sandbox IN FEATURES! With sandbox off, tic works just fine.
We eventually need to get sandbox looked at and fixed. I'm no sandbox expert however. If one of the portage people want to take a look at this, I can arrange for access on the spare Indy I have, or if iluxa doesn't mind, access to his O2K system. Meanwhile, I'll use this bug as a place holder/reminder to get sandbox support looked at.
It probably would be possible.
The prefered method would be to fix sandbox and not disable it. Sandbox needs some help with arch-specific code areas.
Assuming I could get access to a system for testing, I'd be willing to take a whack at fixing it.

Some updates on a possible cause for this bug based on a conversation in #mipslinux with ths (Thiemo Seufer) on a fix he did for Debian's fakeroot. Attached as a text file.
Created attachment 56004 [details] #mipslinux fakeroot discussion
What's going on with this beast?
We've actually got a test patch available now that a debian dev worked up to make fakeroot on debian work. The patch itself is a bit of a hack to glibc, but it seems to get the job done for now until a better solution can be devised. I've already tested this patch under o32 and n32, and it seems, for the most part, to make sandbox work on mips for the first time. Glibc seems to still have a problem -- I had a bus error crop up on me in the sunrpc section, which indicates a memory leak or something was still occuring somewheres under sandbox. I've sent the patch to eradicator already for inclusion in glibc-2.3.5 until the better fix is engineered (likely for binutils). As for this bug, probably good to keep it open until we manage to get a real fix.
where are these magical patches ?
The old 6645_all_glibc-mips_shn_undef-hack.patch is what the Debian folks used to temporarily resolve their fakeroot problems. I don't know if they ever worked up a real solution (which was to be done in Binutils). I don't think I've tried Sandbox is ages.
could you test out latest sandbox (like 1.5) on a mips system ? i dont have any mips systems up and running and all the ones i had ssh access to seem to be dead
Joshua, any progress on this?
I haven't seen any issues on my mipsel n32 yeeloong with sandbox... noticed it's in FEATURES and noticed it under use when cancelling a emerge --regen, so did some tests (and found out it's been in my FEATURES all along): yeeloong ~ # sandbox ============================= Gentoo path sandbox ============================== Detection of the support files.

I think you missed this during the compile... :) ../../sandbox-2.3/libsandbox/trace/linux/arch.c:21:3: warning: #warning "trace: sorry, no support for your architecture" I see that we need to implement what looks to be a pretty trivial piece of code in libsandbox/trace/linux/mips.c, but is there some other component missing? Something about glibc?
no, the trace code is only needed for static tracing via ptrace. dynamic tracing should work fine. if all the tests pass, then that's a pretty good indication that things are working ... but only doing full world emerges would tell you otherwise ...
I've been building stages and testing packages with sandbox enabled and haven't hit any problems. The test suite also passes as mentioned. I think this is fixed. :)
