The example I showed is with all your committed changes included. I expected only one NetManTask at a time, but I did not realize it would be stopped and restarted. It would be nice to know what memory is allocated but not freed. It may not be leaked if it is for resources that are used by other tasks, but still it would be nice to have all the memory properly accounted for. Below is my startup sequence. This may be AP auto-starting and then stopping, followed by client mode starting from my script. Without the modem running, there might be no interfaces up between those two operations. -- Steve Welcome to the Open Vehicle Monitoring System (OVMS) - Async Console I (1982) ovms-mdns: Starting MDNS I (1982) ssh: Launching SSH Server I (2012) version: Set version I (2012) script: Running script /store/events/system.start/startmeup I (2012) wifi: flush txq I (2012) wifi: stop sw txq I (2012) wifi: lmac stop hw txq I (2022) wifi: Deinit lldesc rx mblock:4 I (2022) wifi: wifi firmware version: ebd3e5d I (2022) wifi: config NVS flash: enabled I (2022) wifi: config nano formating: disabled I (2022) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE I (2022) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE I (2032) wifi: Init dynamic tx buffer num: 16 I (2032) wifi: Init data frame dynamic rx buffer num: 16 I (2032) wifi: Init management frame dynamic rx buffer num: 16 I (2032) wifi: wifi driver task: 3ffe5ea0, prio:23, stack:4096 I (2032) wifi: Init static rx buffer num: 4 I (2032) wifi: Init dynamic rx buffer num: 16 I (2032) wifi: wifi power manager task: 0x3ffe7e14 prio: 21 stack: 2560 I (2042) wifi: mode : sta (30:ae:a4:37:1b:84) I (2042) netmanager: WIFI access point is down I (2052) esp32wifi: AP stopped Starting WIFI as a client to Revelstoke...
