Error in module (Ieee80211MgmtSTA)- please help

[Adel]

Hello,

I have a simulation that includes mobile hosts with a number of interfaces. It all worked fine when each host has only 2 interfaces. When I raised the number of interfaces to 5, I got this error:

<!> Error in module (Ieee80211MgmtSTA) HIPWirelessNetwork_Multihome.mobilehiphost1.wlan[4].mgmt (id=130) at event #2263086, t=56.336093878931: Model error: processScanCommand: scanning already in progress.

In the original simulation (with 2 interfaces), these lines were added to the ini file:
# wireless configuration
**.wlan[*].agent.activeScan = true
**.wlan[0].agent.channelsToScan = "1 2"  # "" means all
**.wlan[1].agent.channelsToScan = "3"  # "" means all
**.wlan[2].agent.channelsToScan = "4"  # "" means all
**.wlan[*].agent.probeDelay = 0.1 s
**.wlan[*].agent.minChannelTime = 0.15 s
**.wlan[*].agent.maxChannelTime = 0.3 s
**.wlan[*].agent.authenticationTimeout = 5 s
**.wlan[*].agent.associationTimeout = 5 s

The red lines were removed in the second simulation (with 5 interfaces), because otherwise, I got a different error much earlier....
I have no idea what those lines mean but I think that the problem refers to them.
I attached the whole ini file.

I would really appreciate it if someone could help me solve the problem.
