This article describes the issue of J-Web being unable to rad the session log of large policies.
The session log is configured as follows:
root@SRX650-b> show configuration system syslog file policy_session { user info; match RT_FLOW; archive size 30m world-readable; structured-data; }
This is a limitation, as the allocated memory is 20M. If you need to read large traffic logs, use the syslog server to store them.
