Stop processing iRule by referencing a variable

Which LTM version are you running? I did a quick test on 11.4.1 and reject; event disable all, return; works as expected.

Can you open a case with F5 Support on this. It should "just work".

 tmsh list ltm rule reject*
ltm rule reject_1_rule {
    when HTTP_REQUEST {
        if {[HTTP::uri] starts_with "/reject"}{
                log local0. "Calling reject"
                reject
                event disable all
                return
                log local0. "Called reject"
        }
}
when HTTP_REQUEST priority 501 {
        log local0. "Called reject (501)"
}
}
ltm rule reject_2_rule {
    when HTTP_REQUEST {
        log local0. "reject_2_rule"
}
}

/var/log/ltm output showing the second iRule doesn't get triggered:

Mar 31 20:47:30 ve11a info tmm1[8891]: Rule /Common/reject_1_rule : Calling reject
Mar 31 20:47:30 ve11a err tmm1[8891]: 01230140:3: RST sent from 10.1.0.120:80 to 10.1.0.111:46397, [0x1776da3:4998] iRule execution (reject command)

If I comment out the return statement in the first iRule, I see the rest of that event executed but not anything from the second iRule. This is expected.

If I comment out the return and event disable all statement in the first iRule, I see the rest of iRule 1 executed as well as the second iRule. This is also expected.
