They are separate issues.<div><br></div><div>I'm getting regular memcache errors like SYSTEM ERROR or TIMEOUT for just normal script cache_fetchs. They don't happen a whole lot, but when it does, I get like 10-15 of them all at once. And like I said, it doesn't appear to return negative so call processing kinda fails instead of letting me do the proper action when the key is missing. </div>
<div><br></div><div>The errors I'm getting with distributed dialog profiles and ratelimiting are different. I'm using the prefix modparams for dialogs and it appears to be truncating those prefixes oddly. Ratelimiting doesn't appear to have the same prefix issue. Ratelimiting however also appears to be broken because I have a perfectly idle box showing counters in rl_list. I'm not really sure what's going on and it's hard to troubleshoot because ratelimiting inserts a very large integer to the backend and I'm not sure what it represents. </div>

I understand you are working with Vlad in troubleshooting the
memcached issues.<br>
<br>
But if I understand correctly, you are saying that you are also
getting errors when using distributed dialog profiles but with
couchbase ? If so, what kind of error you get there ?<br>
<br>

<div>Increasing the -R parameter seems to have made the situation
better, but I am without question regularly running into weird
memcache timeout and system errors. I've tried several different
hardware platforms. Point to local and remote memcache servers.
Different memcache libraries and server versions. I've tried
couchbase instead of memcache and I can't get rid of the errors.
I'm really not sure what could be causing them.</div>
<div><br>
</div>
<div>When I get them, the call attempting to process fails, which
is frustrating. I'd expect that the memcache result would return
negative which would trigger a direct db query (which is written
in the script in case the cache object is missing anyway).
However it doesn't do this. It just fails and continues
processing a null return value. Is that behavior expected or a
bug?</div>

<div>Hey All,
<div>Generally I have really good luck with
memcache, but for some reason, I'm having some
issues today. </div>
<div><br>
</div>
<div><br>
</div>
<div>Once I crank this one box up with load, I start
to see these errors flood my logs:</div>
<div><br>
</div>
<div>cachedb_memcached:wrap_memcached_get: Failed to
get: SYSTEM ERROR</div>
<div>cachedb_memcached:wrap_memcached_get: Failed to
get: A TIMEOUT OCCURRED</div>
<div><br>
</div>
<div>I've tired changing the tread count for
memcache. Additional processes.. Heck, I've even
tried putting memcache on other servers and in
other colos. The original memcache is on the same
box and is pointed at localhost (127.0.1.2). </div>
<div><br>
</div>
<div><br>
</div>
<div>I'm hitting it reasonably hard, but it should
keep up. About 10k ops a sec. I see it run great
for like 2 minutes, then it hangs for like 4
seconds, then picks back up for another 30 seconds
or so.. goes that like on and off. </div>
<div><br>
</div>
<div>Any idea of what could be wrong? </div>
<div><br>
</div>
<div>Thanks,</div>
