These firewalls also have dhcp enabled since there is only 1 site that has a windows server, this is our main site which is the largest (~80 users).
Last week we started having problems with the firewall in the main site...
It stopped handing out new IP-adresses, and it won't let me login to the management console.
However it is still routing internet traffic for the clients that already had an IP and the VPN connections between the sites remain active, though they seem to be a bit unstable.
It's running the latest version of the firmware (4.3.4-2)
I've tried restarting it several times by turning it off and back on, but they problem remains. (web-interface won't load so I can't login, telnet won't work either)
Is there anything I can try besides doing a factory reset and configuring all the settings again?
The other firewalls are still running an older version of the firmware ( 3.0.7-29) and they are not having any problems...
Should I downgrade the firmware of the affected firewall?
I wouldn't touch the srx until you find out if any changes have been made by the isp at that location. If nothing has changed on your network and something like this happens, generally the problem is outside your network.
No changes have been made to the ISP or internet connection.
I already did a factory reset of the firewall last week, and reconfigured it from scratch, but the next day the problem occured again. Still have to try downgrading the firmware to see if this helps.
In the log there's also a bunch of error messages like the ones below:

I've also found this thread where someone suggests it's because of heavy load (maxed out traffic)
I guess that's the case for us too. Maybe it's time to look for a new firewall with higher throughput...
The log messages here could possibly indicate a hardware issue as well. I'd try the firmware downgrade and then get in touch with netgear support as these have lifetime support and warranty afaik.
