vxdbd high cpu usage @ hpux

  There is evidence vxdbd daemon is consuming too much cpu and following its behaviour has many EPIPE errors on writes.

See first column:

$ grep " write" ./pid.12331  | awk '{print $4,$5, $7, $9, $16,$17}' | sort | uniq -c | sort -rn

45355 pid=12331 ktid=20116 write err=32 A0=0 A1=6

45219 pid=12331 ktid=20117 write err=32 A0=0 A1=10

43862 pid=12331 ktid=20118 write err=32 A0=0 A1=11

40211 pid=12331 ktid=20121 write err=32 A0=0 A1=13

39893 pid=12331 ktid=20120 write err=32 A0=0 A1=12

 

We think restarting the service could eliminate such condition. Of course the above as a workaround. There is a patch which has some fixes for it , i.e.

PHCO_41073;

Before trying a restart of the service i.e. as per manual documentation:

To start the vxdbd daemon

 Use the vxdbdctrl start command:

/opt/VRTSdbcom/bin/vxdbdctrl start

 

To stop the vxdbd daemon

As root, use the vxdbdctrl stop command:

/opt/VRTSdbcom/bin/vxdbdctrl stop

Our question is:

Q. Is it safe to restart vxdbd daemon with no colateral impact on production services due the nature or extension of vxdbd's functionality?

Best Regards.
