SSL VPN doesn't work anymore

noc_aba

Hi, on a USG1900 (V4.35(AAPL.2)),  after two months people were used to connect via SecuExtender, SSL VPN doesn't work anymore. The SSL VPN client logs out right after it logs in (1-2 second max). In the syslog file we  have just the loggged in, logged out records, and a few records like these

..... src="0.0.0.0:0" dst="0.0.0.0:0" msg="SSLVPN deamon is not availbale." note="" user="unknown"....
We didn't find any way to get SSL VPN working properly again, so we had to reboot !
Does anybody esperienced something like that ?
many thanks
bye
