<tt>Hi Brett,<br>
<br>
Vlad fixed the prefix issue with dialog profiles and Razvan will
take a look on the ratelimit issue. This will fix the usage with
couchbase ;).<br>
<br>
It remains to investigate the memcached issue.<br>
<br>

<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>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>
