Max limit for REST sessions reached with SAN Brocade Rest API

Hi.

I configured two our Brocade SANs to be monitored by Rest API and have the same issue on both.

After 15 -20 minutes of SAN scanning, the Max limit for REST sessions reached error is shown in the log and no more data are collected.

Here is part of its log:

2025-11-04 11:40:00: [SAN_A] Cannot login to Rest API! Exiting... 

2025-11-04 11:40:00: [SAN_B] Cannot login to Rest API! Exiting...

The XorMon creates multiple Rest API connections and after it creates three of them, error rised.

admin> mgmtapp --showsessions

The following is the history of logins to the switch from external applications

(Login Timestamp, IP Address, User Account, Application, SessionId, Current VF, Auth Token, Protocol, UUID):

. . .

The following are the sessions from the external applications that are currently active:

2025/11/04-12:16:05.393245, 192.168.xxx.yyy, Monitor, libwww-perl/6.68, d7764c143b6be7bc694fa38e36d2f905676348694c13dacb757f859b77a27c31, -1, No, HTTPS, None

Both SANs have the same, standard Rest config with enabled KeepAlive as described at https://xormon.com/install-network.php#SAN-RESTAPI:

admin> mgmtapp --show

 REST Configuration:

    Interface State: Enabled

    Effective Protocol: HTTPS only

    HTTP State: Enabled

    Session Count: 3

 HTTPS Configuration:

    KeepAlive : Enabled

    KeepAliveTimeout : 15sec

Is there something I am missing? Where can be the problem?

Regards,

Zoran
