@Adel-Magebinary Can you provide some additional context about what was happening when the crash occurred? It looks like your system doesn't support stack traces, so it's hard to identify the root cause from what you provided.
on one place it says terminated by SIGABRT, but later crashed by signal: 11, si_code: 1 and also crashed by signal: 4, si_code: 1.
@Adel-Magebinary did this version of redis (any other versions of redis), ever worked for you on SmartOs? can you find out which are signal 11 and 4? are these SIGSEGV and SIGILL?
@madolson the system is running alpine image from your latest repo on dockerhub. @oranagra The kill signal changed after I changed the Redis configuration oom-score-adj to yes.
Yes the older version worked for me. I think it was 4.x worked fine with stop-writes-on-bgsave-error no.
The Redis was pumped constantly by Magento 2.4.2 cache.
I just feel like cpu threads counts are the issue because SmartOS exposes all CPUs to the container and only configured cpu threads can be used. Maybe redis is thinking wow, 32 threads CPU, let's use all of it whereas only 8 threads are allowed?
# It is possible to pin different threads and processes of Redis to specific
# CPUs in your system, in order to maximize the performances of the server.
# This is useful both in order to pin different Redis threads in different
# CPUs, but also in order to make sure that multiple Redis instances running
# in the same host will be pinned to different CPUs.
#
# Normally you can do this using the "taskset" command, however it is also
# possible to this via Redis configuration directly, both in Linux and FreeBSD.
#
# You can pin the server/IO threads, bio threads, aof rewrite child process, and
# the bgsave child process. The syntax to specify the cpu list is the same as
# the taskset command:
#
# Set redis server/io threads to cpu affinity 0,2,4,6:
# server_cpulist 0-7:2
#
# Set bio threads to cpu affinity 1,3:
# bio_cpulist 1,3
#
# Set aof rewrite child process to cpu affinity 8,9,10,11:
# aof_rewrite_cpulist 8-11
@Adel-Magebinary so it crashed right on startup, and it never worked for you in that configuration / setup?
@oranagra it doesn't crash when it starts. It starts when there is sadd into smembers from Magento 2. And I did not enable cpulist configs.
@Adel-Magebinary AFAIK SmartOS is a Solaris based system, so we could be running into some unexpected compatibility issue here and unfortunately we don't even have a backtrace to work with because of the alpia/libmusl image. Is it possible for you to see if it reproduces on a non-alpine image?
@yossigo I should be able to easily reproduce the issue with buster images. I will get the team to reproduce it and post it back tomorrow.
@yossigo here is a reproduction of crash, backtrace from Redis 6.2.2-buster image when it is crashed

lol I guess "the cpu guess" were right :)
/lib/x86_64-linux-gnu/libpthread.so.0(+0x12730)[0x7fffee9fd730]
@Adel-Magebinary i think this line is part of the signal handler (which prints the stack trace).
note that the EIP in the signal info is pointing dictAddRaw
@oranagra yea, the issue might come from this line
entry = zmalloc(sizeof(*entry));
That the redis is trying to allocate the memory for the entry but libpthread.so somehow kills it.
Some more info after setting CPU threads.
Fast memory test PASSED, however your memory can still be broken. Please run a memory test for several hours if possible.

it's an access violation in (segmentation fault in dictAddRaw), not in any other function (unless inline), and certainly not in any other library. dictAddRaw doesn't call any libpthread.so function (not directly and not indirectly). what happens is that a signal handler is executed and it prints it's own stack, that can include the signal handler function (we skip it), and the function that called it (a function in libpthread.so)
@oranagra
Got it! I have collected some more info for you from the old threads in smartos discussion. This issue is smashing us a little bit hard as the redis is down, the site crashes with it :(

This issue is smashing us a little bit hard as the redis is down, the site crashes with it
@Adel-Magebinary is this a regression? did this setup used to work and stopped after some change / upgrade?
@oranagra this setup used to work with the lower version of Magento 2.3.5. Then recently we upgraded to 2.4.2 and upgraded redis to 6.2.2. Then the crash has started. I believe the volume of communications between Magento & Redis increased is the change.
@oranagra anything else that I could do to help you with replicating this issue?
@Adel-Magebinary maybe you can try downgrading back to the redis version that used to work (use it together with the new Magento). Or try running redis with valgrind in some way.
i tried disassembling the code dump from the crash log, i think the crash is around the hashing of the member name, but so far it doesn't help conclude what's the problem.
@Adel-Magebinary Unless I'm missing something out here, the discussion group links you've included above refer to similar unexplained crashes with Redis 5.0.6 and 4.0.14.
Assuming this is indeed the case, it is not really a regression with Redis and more likely some memory management issue with SmartOS/Linux containers.
updates:
Tried the latest redis with kvm images. It stopped crashing. @jasonbking
I don't work at Joyent anymore and don't have anything requiring the use of Redis at the moment, so I don't think I'm going to be able to be of any help at the moment. Maybe trying to run it natively instead of in LX (maybe also using libumem since that can optionally also include things like double free and buffer overrun detection via environment variables) and see if it still crashes -- that would at least provide more diagnostic information that could pinpoint the problem.
At minimum, it might be useful to verify the actual statement causing the crash (it sounded like the one identified was just a guess). If addr2line can't identify it, running /native/usr/bin/dis -F dictAddRaw /path/to/redis/binary and look around offset 0x16b could also help.
Didn't you say that you tried the latest and it stopped crashing?
P. S. I don't recall many of the details about this thread, can you remind me how come the initial log doesn't contain a stack trace, but the later one do... ?
@oranagra The stack trace is the same as what I posted. it did not crash on SmartOS KVM Redis. It still crashes on lcx containers. I have launched the thread on smartos mailing list here (https://smartdatacenter.topicbox.com/groups/sdc-discuss/T8ae7feef3247f821-Mc2075cd63b885d7a18f29034).
