You're the first one to report this bug :-)

Not that I know, but I do modify some search code associated with
TCP, UDP, and raw sockets.  Were you running any aplications that would
have been creating new sockets at these times?  Now when you say 'periodically'
how often?  At regualr intervals?  I'm wondering if there is some sort of
TCP timer that is firing and executing a long search with a lock held.

Just for for a sanity check: what NIC are you using, and have you
run this same kernel version without VRF support?

Thanks!
