Brett,
I understand you are working with Vlad in troubleshooting the memcached
issues.
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 ?

Bogdan,
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.
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?
Thanks!

Hey All,
Generally I have really good luck with memcache, but for some
reason, I'm having some issues today.
Once I crank this one box up with load, I start to see these
errors flood my logs:
cachedb_memcached:wrap_memcached_get: Failed to get: SYSTEM ERROR
cachedb_memcached:wrap_memcached_get: Failed to get: A TIMEOUT
OCCURRED
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).
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.
Any idea of what could be wrong?
Thanks,
Brett
