automount problems


I have a Yosemite Mac Mini with performance problems. When looking at the disk activity with opensnoop I noticed that automount is performing tons of accesses as follows



UID PID COMM FD PATH
0 1124 automountd 4 /etc/auto_home
0 1124 automountd 6 /etc/auto_home
0 55536 od_user_homes 5 /System/Library/OpenDirectory/request-schema.plist

0 1124 automountd 6 /usr/libexec/od_user_homes
0 55541 od_user_homes 5 /System/Library/OpenDirectory/request-schema.plist
0 55541 od_user_homes 7 /usr/libexec
0 55541 od_user_homes 7 /usr/libexec
0 55541 od_user_homes 7 /usr/libexec/od_user_homes


Hundreds of access per second. Is this normal? What could be wrong?
