Postgres using 99% CPU

Hi,

I have vcu 3.3.2, running fine for several weeks.

It s been a week that vcu is at 100% CPU due to postgres :

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

5991 postgres  20   0  102m  47m  35m R 99.9  1.3   3:03.04 postgres

    1 root      20   0 10548  844  712 S  0.0  0.0   0:00.37 init

    2 root      20   0     0    0    0 S  0.0  0.0   0:00.00 kthreadd

    3 root      20   0     0    0    0 S  0.0  0.0   0:00.06 ksoftirqd/0

No network issue, disk usage is good, data collecting is still occuring (i can check the monitor tab)

but I can't view any report nor got the automatic report emailed.

When I try to generate a report it automatically cancel it :

Starting report “Monthly Usage.”

Production of the Monthly Usage was canceled.

I try to delete old data but it looks like it never did something. One hour later, I rebooted the appliance and still got Postgres loading vcu appliance.

Can you advise me ?

regards,

vinny
