solaris 8/9, memcached consumes all CPU after request

[Jim Lawson]

Hi memcached at lists.danga.com,

We're trying out memcached on our web farm, which is mixed Solaris and 
Linux, mostly Solaris.  It looks pretty cool.  It seems to work fine 
under Linux (RHEL3, 2.4.21-EL3 kernel.)  However, under Solaris 8 or 9, 
after the first request is answered and the TCP session is closed, 
memcached starts looping and consuming 100% of the CPU it's running on.

Running memcached 1.1.11, libevent 0.9.

Running EVENT_SHOW_METHOD=1 /usr/local/bin/memcached -u nobody returns:
libevent using: devpoll

I have attached an edited transcript of "truss" against the running 
memcached which shows the behavior.  This may be just a configuration 
issue, but I'm afraid it's out of my league.  Any pointers?

Jim
