Router just spontaneously became unstable, I sent a supout but has anyone seen this?

/ip dns print returned "action timed out"
/file print was very slow to return results
/system sup-output took an extremely long time to create (6-7 minutes (x86 xeon 3ghz)
/system reboot took a long time to execute
connecting via SSH or telnet was fast but took a long time (2 minutes)to produce a prompt after the "mikrotik" logo scrolled by.

Version 4.11 dude 3.6 on x86 xeon 3ghz. [Ticket#2010092566000081]
