I ran into a truly weird error today. I was building a very simple test script to load up my cache system with a lot of crap. This was the script I used:
<cfloop index="x" from="1" to="3000"> <cfset id = "cache_#x#"> <cfset cached = cacheGet(id)> <cfif isNull(cached)> <cfset value = createUUID() & createUUID() & createUUID() & repeatString("foo", 250)> <cfset cachePut(id, value)> </cfif> </cfloop>
Nothing crazy there, right? Well upon running this code I immediately got:
IP_ADD_MEMBERSHIP failed (out of hardware filters?)
net.sf.ehcache.CacheException: IP_ADD_MEMBERSHIP failed (out of hardware filters?)
I googled - and ran across a few things, but nothing made sense until Brian Kotek pointed out the following URL:
This led to the following Microsoft Tech Note:
And that did the trick. This "Media Sense" feature (which by the way impacted my Windows machine but not a coworker) was the culprit. As soon as I did the regedit (wow, it's been a long time since I did one of those) and rebooted, everything worked perfectly.
