I have a Nokia firewall which users can getting disconnected 2 or 10 minutes later after been connected. I checked the system log for this I getting the following error "[LOG_CRIT] kernel: vpnk_fini_cryptxl_cxt: ERROR: didn't to destroy context for esp_sa 0xa809ac1c because vpnxl_cxt_initialized=0 ". I can not find the meaning of this error. Does anyone knows about this error? Your help will be greatly appreciated.
