I am seeing 2.8.2 crash on multiple linux machines about once every 24 hours

by crash I mean it just closes itself one min you see shares being accepted the next min you see  $ command prompt - no error msg given



 dont know if its a segmentation fault or what but it happens once a day

This doesn't help identify or fix the problem at all. Please get some information and open an Issue. I suggest building with CFLAGS="-ggdb -O0" (add this onto the ./autogen.sh line) and running with "ulimit -c unlimited; valgrind bfgminer <your options> --debuglog 2>debug.log"

No, most of such issues tend to come from cgminer-originated changes. Also, cablepair is presumably using ModMiner devices, which cgminer doesn't work with at all (because they stopped merging updates to the driver before the production devices existed).

You really should actually check some of the things you say ...
instead of making up stuff ...
You didn't send pull requests for fixing MMQ ...

No. If the beta Stratum branch gets enough testing it might make 2.9.0.

NEW VERSION 2.8.3, OCTOBER 18 2012

2.8.1 made an old, rare dereference-after-free error a lot more common in some cases (due to locking the output mutex for new debug info) so I finally got a proper chance to track it down. That crash, along with a variety of other bugs (including some scrypt fixes from Jake and Con) have been fixed for 2.8.3.

2.9.0 is still in the works to bring the long-anticipated X6500 support (which is now coming along nicely). Depending on testing and reviews before then, it may also include solo mining and/or Stratum support - so if either of those features are important to you, please test the latest code (in git branches) and let me know!

Human readable changelog:
  • Various bugs fixed, no new features.

Full changelog
  • Update to libblkmaker 0.1.3
  • Use explicit host to BE functions in scrypt code instead of hard coding byteswap everywhere.
  • Ease the checking on allocation of padbuffer8 in the hope it works partially anyway on an apparently failed call.
  • Round target difficulties down to be in keeping with the rounding of detected share difficulties.
  • String alignment to 4 byte boundaries and optimisations for bin<->hex conversions.
  • Fix GPU memory allocation size for scrypt
  • Fix access violation with scrypt mining
  • Bugfix: Only free rpc_req after using it, not before
  • Bugfix: Increment work->pool->staged inside of mutex to avoid work being freed (and staged decremented) before we dereference it
  • Revert "No need for extra variable in hash_push.": The extra variable is needed to avoid a rare dereference-after-free error.
  • In opencl_free_work, make sure to still flush results in dynamic mode.
  • Workaround: Debug log only after dec_queued, to make a free/use race more rare
  • Bugfix: Remove redundant \n in debug messages
  • Bugfix: Free rpc_req in pool_active and longpolls
  • README: Explicitly provide Ubuntu package name for libjansson-dev
  • Bugfix: Include flash_led bool in cgpu_info for Icarus-but-not-BitForce builds, since Cairnsmore uses it
  • Only check work block id against pool's if the pool has a known block id
  • Avoid clearing pool->block_id unless we really are changing pools

Anyone know how to get this to work with a windows utility like restartme or restart on crash? I prefer bfgminer to aoclbf/phoenix, but it crashes leaving my system gobbling power w/o mining. I built a functional .bat, then a .conf file, but neither works with either utility. When the restarters point to bfgminer.exe it re-launches fine, but ignores the config file and just pops up a cmd window. Huh

I'd rather figure out what's going on that causes it to crash for you. Can you go into more detail on that?

BFGMiner looks for the config file named bfgminer.conf in the "working directory" it's launched from on Windows. Hopefully those programs let you specify that?

Seems to me that you would add "__" to the beginning of each line to block that line out of your config file.

BFGMiner looks for the config file named bfgminer.conf in the "working directory" it's launched from on Windows. Hopefully those programs let you specify that?

I get a BSOD/machine check exception on my main rig(i7 970) when running bfgminer usually within a couple minutes. I previously thought it was a problem with GPU memory underclocking, due to the fact that I could induce a crash in bfgminer by specifying a memclock under 625mhz. However I've since set memory clock as low as 166mhz on multiple rigs using aoclbf and then mining with bfgminer w/o issue. I'll set up a log file for bfgminer before restarting it. The program happily mines all day and night on my older s775 rig with three vid cards and speeds are reported to be only slightly higher than phoenix, but I believe phoenix is exaggerating and the gap is wider than reported.

I have bfgminer.conf setup and working when manually started. Restart on crash allows a modified path, but it doesn't seem to pick up the info in the .conf file when restarting the program and just spits out the "no url" message. Perhaps I'll try transplanting bfgminer to C:\ and see if that helps.

BFGMiner can do the same as described in this post or not?
In theory, though I haven't tested it lately. If it doesn't work, feel free to open a bug report on github for it.

Additionally, you can use BFGMiner with Bitcoin next-test to get native longpolling from bitcoind/Bitcoin-Qt.

It's ALIVEEEEEEEEEEEEEEEEEE!  Shocked



What I don't understand is why miner submited to pool 1. Did pool 0 went down temporaly (why there's no message about it?),
so miner temporaly switched to pool 1? I haven't set any specific multipool strategies, e.g. miner uses the default one (failover).

One other thing, a bug maybe - occassionaly, at around 2 minutes since startup, and only once, miner shows message "Pool 0
not providing work fast enough". I have increased both queue and scan-time since I can't find anything else that could, from
my noob perspective, affect the issue but none of those two helps.
i had this problem too with the submitting problem. i have failover too and the pool didnt fail yet its getting submitted somewhat randomly, this sucks Sad hope for a fast fix Smiley

Without --failover-only, BFGMiner will use other pools' work (eg, from the longpoll) in some cases. Likely the share you refer to was found before updated work had been retrieved from your local bitcoind yet.
