Bogdan,<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>Once I crank this one box up with load, I start to see these
errors flood my logs:</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>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>Any idea of what could be wrong? </div>
