DHCP Service Stops and Won't Restart

[amitis5]

Hi All,

I have an install in place with supermicro, xeon D, 8gig ram, 256 gig ssd.  We are running an apartment building with it, and it has been going very well.  We have 150 or so VLANs, with 150 or so DHCP running.  I'm not sure why, but over the last couple of days, DHCP service is stopping, and I can't seem to get it to restart without a lot of patience (randomly seems to come back sometimes on its own).  Sometimes a good 30 minutes to come back up after clicking the play sign.  Any ideas on why it would be stopping in the first place?  CPU is running about 20% load (was having some trouble here, but fabian helped with this, net flow was chewing up the processor).  Even after fixing this, I'm still seeing the issue with DHCP stopping. 

Any ideas?

Thanks in advance

Seems i have similar issue where dhcp is down somehow as even in static list devices do not get ip.
I assume it is similar case.

In GUI when i hit start it still seems that it is not starting.

Maybe i try another clean install soon.

Did reinstall and set dhcp up in console after install and now it seems to work better.
