Mongod is using 1 cpu core while doing absolutely nothing. There is nothing reading from , or writing to mongodb and yet 1 cpu core is at 100% (most of it is iowait) Fri Dec 11 10:11:07 connection accepted from 192.168.7.142:49806 #2 stracing the process gives: rt_sigreturn(0x16) = -1 EINTR (Interrupted system call) ) = 0 ) = ? ERESTARTSYS (To be restarted) (the above output is constantly repeated) Killing the process and starting it again returned to normal idle usage |
