The log only shows the first thread, not the others. There are also no
timestamps so I don't know the scale. But this looks quite normal. There are
incoming requests and the epoll mask is modified.
I had a virtual machine dieing under nscd 99% load for many many minutes, as
soon as I did an 'service nscd restart' the machine resurrected, and nscd
stopped using 99% cpu.
what kind of information do you need to analyze this problem ?
is strace sufficient?
attach gdb ?
Should work nicely in current version.
